USFULL LC1-D series AC contactor, popular in industrial control and protection. 3pole and 4pole, AC coil and DC coil both available.

What is an AC contactor?

The contactor is the part of the air conditioner that controls the flow of electricity into the unit. When you turn off your AC, the contactor goes up, blocking power. By the same token, every time you turn on the air conditioner, the contactor is lowered, allowing electricity to power the system. Once your home reaches the temperature set on the thermostat, the contactor goes up again.

USFULL contactor is suitable for using in the circuits from 24V up to the rated voltage 660V AC 50Hz or 60Hz, rated current up to 95A, for making, breaking, frequently starting & controlling the AC motor.

Contactors and overload relays are the largest selling line of contactors and starters in the world. They offer high reliability with long mechanical and electrical life and the most complete line of accessories in the industry.

LC1-D 09~32A 10 is Aux. contact normally open, 01 is Aux. contact normally close.

LC1-D 40~95A One normally open and one normally close Aux. contact

Combined with the auxiliary contact block, timer delay & machine – interlocking device and so on, it becomes the delay contactor, mechanical interlocking contactor, star – delta starter. With the thermal relay, it is combined into the electromagnetic starter.
