Cam starter QS5 is mainly used to start,stop,forward or backward directly three-phase asynchronous electric motor with AC 50/60h

Cam starter QS5 is mainly used to start,stop,forward or backward directly three-phase asynchronous electric motor with AC 50/60hZ,voltage up to 500v and capacity up to 30HP.

It can also be used to change over the circuit from one kind to the other.
