S-K series AC contactorDetailed product description：

Applicable:
The S-K series AC contactor is mainly used to connect/disconnect long-distance lines in power distribution systems. The frequency of such lines is AC 50/60Hz, with a rated voltage of 660V. It can also be used in AC-3 with a rated voltage of 380V and a rated current of 150A to connect or disconnect remote lines. It can also frequently start and disconnect 3-phase motors, and is connected with Th-K thermal relays to protect the lines from overload.
