The product is intended for operating ZN28 indoor HV vacuum breakers under
the voltage of 10-35 KV and various kinds of other circuit breakers which have
the equal switching work.It has functions of over current protection and
under-voltage releasing protection.The output angle is from 50 °to 55 °, and the
mechanical life is 20000 times.
