The clap contactor is mainly used in the control of AC and DC circuits. With its ability to withstand high load rates and high operands, it is widely used in metallurgy and iron and steel, port machinery, electric locomotives, mining, paper, petroleum, chemical and other industries .

k. Adapt to various applications under severe conditions
Ideal choice under heavy load conditions
The snap-in contactor usually has two coils: the pull-in coil and the separation coil. After the contactor is closed, it is locked by a mechanical device, and the coil does not need to be charged. The contactor remains closed until the separation signal is sent by the separation coil, and the contactor opens.
