ZN12-40.5(3AF) Indoor High Voltage Vacuum Circuit Interrupter
ZN12-40.5(3AF) circuit breaker use main conductivity loop and operation mechanism around arrangement form. Circuit breaker uses dedicated spring operation integrated with switch. The main loop uses excellent vertical magnetic field vacuum arc-extinguish chamber. The circuit breaker has small volume, steady function, safety operation.The technology of circuit breaker is 3AF with strong breaking capacity, long mechanical lifetime, and excellent technical performance.The actuator with complete functions can be operated by AC, DC, or manual operation.
