The bodies of the circuit breaker interrupter system design into one dedicated Siemens 3AF type spring operating mechanism, the operation of the motors of AC and DC energy storage, and can also be used for manual operation. The design of this product: 350mm, 400mm, 460mm and so on a variety of phase distance, users with different types of switchgear with more convenient to use. Can be used in fixed cabinet XGN17-40.5 in JYN1-40.5, KYN12 40.5 cabinet used. ZN12-40.5 vacuum circuit breaker with KYN -40.5 KYN1-35 of GBC-35 series switch cabinet supporting the main switch. Circuit breakers installed in the switch cabinet handcart, as mobile unit at the same time the circuit breaker can also be installed in the switch cabinet XGN-40.5 fixed installation of the circuit breaker mechanism and switch it special spring-loaded actuator, AC DC energy storage, can also be used manually operated.
