Sell Air Circuit Breaker FTW2

Air circuit  Breaker FTW2 applies to the distributing net with AC50Hz, rated working voltage 400V or 690V, and rated current 200A-1600A. It can be used to distribute electricity and protect the power equipment from the danger of overload, under-voltage, short-circuit and single-phase etc. The circuit breakers with 630A and below are used to operate electromotor directly and control the electromotor's occasional start or stop.

With the most compact size, multi-protection function and precise selective protection, this intelligent  type of air circuit breaker can improve the security for providing power and avoid unnecessary power-stop. Meanwhile, with communicative interface, this type of air circuit breakers is convenient to distribute automatically so as to satisfy the requirements of controlling center and automatic system. In addition, it has the isolation function when it is not installed with intelligent controller and transducer.
