Winston home AC contactor is mainly used in AC 50Hz (or 60Hz), rated working voltage up to 400V, rated working current up to 100A circuit, to control the low-inductive load of household appliances and similar applications; also can be used to control the home motor load, At this point the control power should be reduced accordingly.
B series contactor eliminates the obvious knock on the traditional contactor at the moment of suction and eliminates the low-frequency sound in the contactor work. It applies to the vast majority of building electrical control field, creating a super quiet environment.
In the working state, the contactor needs to maintain a long time of energization to keep the coil in contact. In this process, a large amount of electric energy is needed. The B series contactor reduces the contactor's power greatly by optimizing the electromagnetic system.
Winston home contactors can be used to remote control applications in alternative networks:
1. Lighting, heating, ventilation, roller blinds, sanitary hot water
2. Mechanical ventilation systems, etc
3. Load-shedding of non-priority circuits
