There are times wherein we need power supply very badly, especially during a power outage. For instance, you have deadlines to meet so you need to use the study room, or you want to use the living room where you can spend quality time with the family. How about if you have a sick person who needs air conditioning and medical equipment in a room? Or what if you have a party that needs uninterrupted power at a specific area?

Hospitals require back-up power application when blackouts happen. They must continue operations even during power outages for the sake of the patients. The same can be said for critical operations of other companies.

You need a hassle-free automatic transfer switch. Meiji Contactor Transfer Switch (CTS) is the answer to all the above concerns! You may now conveniently do so during a power outage with Meiji CTS. And you will never overload your generator.

Meiji Contactor Transfer Switch



Usually, homes acquire generators with just the right power to be used for emergency purposes, which means the generators cannot serve 100% of your loads. When you want a certain appliance to be powered up, or only few specific rooms to be lighted, Meiji CTS gives you the versatility to choose and power up only the selected loads. Isn’t that convenient? With its Current Limiter, which provides safety from overloads, your home can never be in danger.

When it comes to back-up power applications, Meiji CTS provides high-quality and reliable performance. Meiji CTS gives you the convenience of using the same feeder lines for the load side during emergency power. There is no need to fix certain loads with an emergency feeder line, and with an emergency panel.

You therefore can save on additional wires, pipings and panel. Yet you get the flexibility of using any loads without worry of overloading the generator. This is because the Current Limiter will automatically cut off power at any overloads, will automatically reset and will allow you to reduce your loads accordingly. In case you have unintentionally used loads more than what the generator can handle, power will temporarily be cut-off, the CTS will automatically reset, to give you time to reduce your load, then emergency power will resume at a pre-set time.

When normal power comes back, the Meiji CTS will automatically transfer power to the normal side. The generator will then also automatically turn off. There is no need again for any manual turning on and off of the circuit breakers or double-throw switches and generator.


Meiji CTS are being used at homes, commercial establishments and even industrial buildings, in a cost-effective package, with outstanding performance, reliability and versatility.

As back-up power sources become more common in residential construction, many homeowners like us have learned about the needs and benefits of transfer switches. Most of us know that in the event of a power supply outage, it is at the very least desirable to power up selected circuits in a service entrance panel to provide limited light, heat, and refrigeration. Having the option of operating a transfer switch or having the peace of mind while the power returns back to normal is a very wise and safe option.

Meiji Contactor Transfer Switch (CTS) is designed for a standby power application. It provides flexibility, reliability and  high quality performance in a compact package. Meiji Contactor Transfer Switch provides fully effective transfer in applications where a momentary loss of power is acceptable during transfer and re-transfers between normal and emergency power supply.

With a manual transfer switch in place, you would first have to make your way to the service entrance panel. Many times, this would be done in the dark with a flashlight in hand. After discovering that the electric utility outage takes longer time, you must manually turn on the switch, allow it to come up to speed and stabilize, and then throw the lever on the transfer switch into the generator position. Prior to switching over to standby power, you would have to shut off individual breakers for non-essential branch circuits.

On the other hand, a Contactor Transfer Switch (CTS) is a transfer switch that brings the accessibility of utilizing the same feeder lines during emergency power, with a current-limiting device that can help you regulate the amount of energy to be given each specific load when the power runs out.

Its primary feature is convenience as it allows you to turn on all the loads you want your generator to give power to. This is because of its current limiter that can detect overloading. So your CTS saves you the hassle of memorizing which breakers are the only ones allowable to turn on, the stress of turning off all breakers and turning them on again once power is back, instead when it senses an overload, the current limiter will cut off power to the contactor.  When this happens, the generator runs at no load, thereby protecting it from any overload. There’s an automatic timer that will bring back power again at the pre-set time of your choice. You then just have to turn off the non-essential loads to avoid another power cut-off. You may also pre-set a time delay of your choice during power transfer to avoid damages to compressor loads due to sudden power surges.

All of these actions take place with no human intervention. This brings less hassle in your part as you don’t have to be walk along the dark way going to your controls.

Because technology makes life easy, Meiji Electric goes with its flow on enhancing our daily lives, whether in residential, commercial or industrial establishments. Every appliance that is connected to the line, and backed up by a generator, needs a transfer switch for shifting power sources when needed. Hence, we encourage you to maximize your generator with Meiji Contactor Transfer Switch.

As technology continues to advance, some might neglect the natural energy we can get from Mother Nature. To be significant, we should utilize what has been naturally entrusted to us and at the same time, enjoy the perks we can get from our natural resources.

Renewable Energy

rERenewable energy, as defined by Wikipedia, is the power that comes from resources that are naturally replenished like sunlight, wind, rain, tides, waves and heat energy stored in the Earth.

Renewable energy substitutes the usual fuels we use in running motors, energy services and electricity generation. The mainstream renewable energy sources are wind power, hydropower (energy in water), biomass (energy from plants materials), geothermal energy (energy stored in the earth) and solar energy.

And because it is widely used all over the world mainly in power plants, business establishments and even in our homes, it results to significant energy security, climate change treatment and a lot of economic benefits.

There is a strong support of promoting renewables sources particularly solar power and wind power. These kinds of energy source provide 19% of electricity generation worldwide including households.” -International Public Opinion Survey

Growth of Renewable Energy

According to the Renewables Global Features report last year, 2013, national renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. Here in the Philippines, specifically in Palawan, there will be a large micro-grid power plant generating clean renewable energy.

Some local residents nationwide have renewable energy technologies (Solar Panels, Wind turbines, etc.) already. With these advances, it would be cost-efficient  for you to have another source of power aside from the usual distributor of electricity power (MERALCO).

You can definitely use renewable technology with or without generators as a substitute for emergencies especially when you experience power outage in a home.

Manual Transfer Switch1

As we are informed, we cannot use both emergency power and normal power (MERALCO) at the same time, or else, it would start a fire or even blow out a house.  In this case, a Transfer Switch is a necessity.

Transfer Switch Utility

With the help of a transfer switch with a built-in interlocking system, may it be manual or automatic transfer switch, we can easily transfer power from one source to another safely.

Meiji Electric offers three types of transfer switches, Manual Transfer Switch (MTS), Automatic Transfer Switch (ATS) and Contactor Transfer Switch (CTS). With MTS and ATS, you can make your home more comfortable during  brownouts. The type of transfer switch that would match up with your generator and/or renewable technology depends on their capacity and ampere ratings.

Normally, we use any of the three in a household setting. But for institutions with industrial setting, like power plants, the MEIJI Automatic Transfer Switch (ATS) is the appropriate one to use. An ATS, by the term itself is a system that automatically transfers your emergency power when normal power is unavailable and automatically transfers back to normal power when power returns. This type of Transfer Switch brings ease and security to you because you don’t need to turn on and off any power source by yourself.


Some home owners find it more convenient to use Meiji Contactor Transfer Switch (CTS). CTS is a transfer switch that brings the accessibility of utilizing the same feeder lines during emergency power, with a current-limiting device that can help you regulate the amount of energy to be given each specific load when the power runs out.

It has an automatic transfer switching which safeguards you and your home from overloading the generator with a current-limiting and automatic resetting of power at your pre-set time.

You can make your home safe and comfortable during a power outage and peacefully enjoy bonding time with the family. The same with corporations, they can work continuously without being interrupted by energy disconnection and other sudden electrical cut-offs. Remember that down-time costs double, you pay for regular work without producing anything.

Technology can really make people’s lives easier without harming the environment.

Thus, Meiji Electric responds to everyone’s needs as we all embrace its continuous development. With Meiji, go along freely with the flow of innovations on green energy.

Manual Transfer SwitchWhat is a Transfer Switch? I bet if you’ve been living for a year in the Philippines, you’ve experienced at least once… nah, I’ll be kind to say at least thrice – of having power shortage or what we would normally call, “brown-out!” So when it happens, you slowly reach out for your handy emergency light to finish whatever it is that you’re doing. But what if you’re cooking using an electric stove when the power got cut? How do you continue? Or when you were watching a really nice movie and the hero was just about to save the day! You were left hanging because of the power outage – what do you do? How do you respond to your kids who desperately need to finish their homework with a strict deadline the next day? Answer: GET YOURSELF A TRANSFER SWITCH!

When we say ‘transfer switch’, we mean transferring power from one source to another. So we can say, from using Meralco power source, we now transfer source to your Genset or Generator. Now, having said this, we can get the logic that you can only make your transfer switch work when you’ve already bought yourself a reliable Genset. In choosing which Genset to buy, you first need to establish what percentage of Meralco power you need or want to work during a power outage. If this is inconvenient for you to compute, then you may just check what loads: wattage and ampere ratings of the appliances you need or want to work. After doing so, then you’re all set for your transfer switch.

Double Throw Switch

Transfer SwitchesNow you may say what about the conventional “Double Throw Switch” that my friendly engineer-technician recommended? Well, aside from it’s unappealing in nature and the need to move the lever up or down; it merely makes up of a barrel bolt that highly risks your (the users’) safety. What do I mean? In light of a transfer switch features, let me help you understand.

A transfer switch is a compact, light weight and very user-friendly mechanical device with a built-in interlocking system that does not allow you to switch on both your Normal power source (MERALCO) and the Emergency line (GENSET). Turning on the Emergency side breaker will automatically switch off the Normal side avoiding any faults on your power source that may cause extensive damage such as fire, explosions and the like to your main panel board. On the other hand, the Emergency side will have to be switched off first before the Normal side can be switched on. This will then be an advantage of the so-called Manual Transfer Switch (MTS). These are available in 2×1 pole, 2×2 pole, 2×3 pole, with models starting from 1A. How about the price you say? As we have already mentioned earlier, your Genset will depend on the loads you want or need to work therefore, the Transfer Switch also depends on the load of the Genset you’re using. So ultimately, the price depends on you. So now, be sure to inform your engineer-technician that you’ll definitely be using a Transfer Switch than a Double Throw one.

Now that you know how to choose your Transfer Switch, how it works and its basics features from the MTS earlier, allow me to inform you of the two other types. Don’t worry, I’ll only brief you into them at least before a sales agent pitches in his or her talk, you are not at their mercy.

Automatic Transfer Switch

An ATS by the name itself is a system that automatically turns on your Emergency Power when Normal Power is out and automatically shuts off your Emergency Power and turns on Normal Power when it comes back in. This type of Transfer Switch highlights convenience and safety for you (the user) as you don’t need to personally turn on or off any power source. And more importantly, like the MTS, it avoids accidentally turning on both power sources.

An ATS is a Circuit Breaker type that is electromechanically operated that does that for you since there is an electromechanical circuitry unlike the normal breaker in your bathroom heater that you have to manually turn on and off. You would just have to fix the loads set on your Generator for emergency purposes.


Contactor Transfer Switch (CTS)

Last but definitely not the least is the Contactor Transfer Switch (CTS). Like the ATS, the CTS’ primary role is to promote safety by automatically turning on and shutting off your Genset in cases of power outages. Its primary feature we can say is convenience. Aside from the above-mentioned, it also allows you to turn on all the loads you want your Genset to give power to. This is because of its current limiter that can detect overloading. So your CTS saves you the hassle of memorizing which breakers are the only ones allowable to turn on, the stress of turning off all breakers and turning them on again once power is back, instead when it senses an overload, the breaker just ‘trips’ or cuts off power. At first, you have to do a trial and error to find out up to how much your Genset can handle. But once you’ve established that, when power is out or comes back, you’ll just have to wait about 3-5 minutes for the delay. This is to protect your breakers from the electric surge when power comes back. So once this has been established… then clap, clap, lights on!

So whether you were cooking a romantic dinner for your spouse, watching a great movie with the family or in desperate cramming mode to finish your homework, when the power gets cut, no worries! You know you have a Transfer Switch doing its work!
