Features 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. Low-inductive load for controlling household appliances and similar applications. Can also be used to control the load of the household motor, and the control power should be reduced accordingly.
