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.

Meiji Contactor Transfer Switch (CTS) is designed to provide matchless performance, reliability and versatility for back-up power applications. It quickly and safely shifts the load circuit from a normal power source to the emergency source, permitting light and heavy-duty loads to continue running with minimal or no outage in momentary losses of power.

Contactor-type Transfer Switch

A Contactor-type Transfer Switch is electrically operated and mechanically held. It operates faster than a breaker-type transfer switch which reduces transfer time. It functions accurately in forming the interface between the generator set, utility power and the consuming electrical equipment. It monitors power sources when power failure happens. The built-in contactors are installed for frequent switching of the load current and commonly used as a part of the motor starters.


When the utility power fails, the CTS will signal the generator to start. If the generator has reached operating speeds with precise frequency and voltage levels, the transfer switch will disconnect the utility source and connect the generator. The design of the CTS contacts makes it impossible for both sources to be connected simultaneously.

After the utility power is restored, the CTS returns the load to the normal power. A generator cool down timer is then initiated. After the cool down period, the generator automatically shuts down the CTS back into monitory mode and stands ready for the next power outage. The CTS also regularly runs test cycles to make sure your backup generator is ready when you need it.

Buildings which utilize a generator power to keep critical circuits running like fire pumps, computer systems, gaming, and hospital equipment should use an automatic transfer switch, particularly CTS. Home circuits will be conveniently electrified when the 100% generator power can be utilized to a preferred area of the house as ordinary ATS can’t.

Every equipment that is connected to the line and backed up by a generator set needs a transfer switch for shifting the power sources when needed.

Make sure to go for a reliable and appropriate automatic transfer switch, especially Contactor-type Transfer Switch to maximize the power usage and experience total convenience during power outages.


With Meiji CTS, your investment is worth it!
