NSW1-3200 Air Circuit Breaker

NSW1-3200 Air Circuit Breaker

NSW1 series “anxele brand” intelligent universal circuit breaker is used for controlling and protecting low-voltage distribution networks. It is generally installed in low-voltage distribution cabinets to serve as a main switch for main protection effect. Circuit breakers with the rated current of 1,000A or below can also be used for protecting motors. The product can provide damp and tropical type (TH type), marine type and 1E circuit breakers, circuit breakers with low temperature of up to -40℃, as well as LCD and LED display circuit breakers.

 

 

 

 

Model and meaning

  • Intelligence, zero flashover, isolating function;
