Tips: What is the Lighting Contactor?
The lighting contactor is a relay switch that controls the flow of current through a circuit that supplies power to the lighting in a given area. They exist remotely and control circuits with higher voltages. If they are directly controlled, they may cause danger to the operator. The lighting contactor switch operates under a lower but safer load and uses an electromagnet to control the high voltage/current circuit.
40 amp lighting contactor with 2 operation modes for sale online, magnetic contactor has 100,000 cycles, coil voltage 220V/110V AC, selectable contactor auxiliary contacts. it pperates at a safer load, optimizes the electromagnetic system to reduce the maintenance power, and provides reliable and convenient lighting control.
