About this item
BCH8s series household AC contactor is mainly suitable for AC 50Hz (or 60Hz), rated working voltage to 400V, rated working current to 100A, controlling low-inductive load of household appliances and similar applications.
It can also be used to control the load of the household motor, and the control power at this time should be reduced accordingly.
Long Service Life: 100,000 full load on and off in AC-7a load category.
Ultra-Quiet: Eliminates the obvious impact of the traditional contactor at the moment of pick-up and eliminates the low-frequency hum in the contactor operation. Suitable for most building electrical control areas, creating a super quiet environment.
Ultra-Energy-Saving: In the working state, the contactor needs to maintain a long-term energization to keep the coil in contact, which consumes a lot of electric energy in the process. The contactor optimizes the electromagnetic system, greatly reducing the power of the contactor.

Rated Control Power Supply Voltage Us(V): AC24V
Rated Work System:
a) Eight-Hour Work System:
This working system is the basic working system, and the free air heating current Ith of the contactor is determined by the working system.
b) Intermittent Periodic Work System:
The rated operating frequency of the contactor under this working system is 30 times/h, and the load factor is 40%.
Action (Operation) Conditions:
When the ambient air temperature is in the range of -5°C to +60°C, the contactor shall be subjected to the rated control power supply voltage to make it heat up to a stable state. The contactor can reliably closed under any voltage at the range of (85% ~ 110%)Us; its release voltage is (20%~75%).
