Operating mechanism
◆ The operating mechanism is of the stored-energy type, i.e., it relies on a spring action with pre-stored energy；
◆The spring can be stored manually by means of a handle on the front panel or electrically using a geared motor；
◆The circuit breakers can be operated remotely by means of closing and opening coils mounted inside the operating mechanism and by using a geared motor to store energy in the springs. If required, they can also be used in conjunction with a monitoring system。
