GMC AC/DC Mini Contactor Motor Protection Switch Low consumption 6A,9A,12A,16A



AC Contactors (Magnetic Contactor) provide remote control of primarily electric motors and compensation & heating systems by cable. They protect the instruments and equipments against overload currents by using thermal relays, for capacitor switching contactor.


While switching on a capacitive circuit, a high frequency and large transient current peaks are produced. Switching of capacitor for a single or one of the capacitor banks are different from each other. Step by step "switching on" operation is more difficult for contactor than capacitor bank. Because during this operation for capacitor bank, compensated current occurs. For this reason selecting of suitable contactors the compensating current must be take into consideration for 50kVAR and above, and for less than 50kVAR can be omitted.





Directly drive contactor by transistor output of PLC


The power consumption of the UKC1- low consumption type contactor is 1.2W.


This contactor can be driven by a transistor output of a PLC or electronic equipment such as photoelectric switch, or a proximity limit switch. Therefore, it is possible for this contactor to directly interface without interface relay for driving a 3-phase induction motor.


Low coil power consumption greatly expands application flexibility. Standard AC coils require 1.8 watts.

Benefits for mini AC contactors:


Low consumption power

Saving panel size

Installation space is reduced to 50% of conventional DC operated contactors achieving high performance.



Main application fields for ac mini contactors: 


Lighting for out-door

Car washing facilities

Crain hoist

Lighting of sports facilities



Vending machine

Painting machine

Show case

It is possible to expand the control wire length since voltage drop in wires is small.






Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.


Lighting control

Contactors are often used to provide central control of large lighting installations, such as an office building or retail building. To reduce power consumption in the contactor coils, latching contactors are used, which have two operating coils. One coil, momentarily energized, closes the power circuit contacts, which are then mechanically held closed; the second coil opens the contacts.
