Operating mechanism
The spring operating mechanism of the circuit breaker stores energy through manual operation, no need. Any external power supply is required, which is convenient and reliable. After the energy storage is in place, it can be operated by closing and opening
The handle is used for closing operation. When in the closing position, it can be accessed directly through the closing and opening handles. The opening operation is performed, and no energy storage is required for each opening operation.
