UKC1-20D3 Air Conditioner Contactor 3P 20/25A ac Coil 24V 110V 220V
UKC1 Air Conditioner Contactor is a core electrical control component in HVAC systems. Its primary function is to control the connection and disconnection of main contacts through an electromagnetic coil, enabling power switching for high-power loads such as compressors and fan motors. This makes it essential for ensuring reliable startup, shutdown, and operation of air conditioning units.
Composed of an electromagnetic coil, main contacts, auxiliary contacts, and an insulated housing, the contactor delivers reliable performance in demanding environments.
The main contacts are responsible for supplying or cutting off power to the compressor and fan circuits, while the auxiliary contacts support control circuit signaling and status feedback. The housing, typically constructed from flame-retardant insulating materials, complies with international IEC safety standards for enhanced operational protection.
