Air circuit breaker FTW1 series apply to the distribution net with AC50Hz (60Hz), rated working voltage 380V (400V), 660(690V), rated current 400A-6300A.

They can be used to distribute electricity and protect circuit and power supply from the danger of overload, under-voltage and single-phase.

This type of air circuit beaker is with functions of intelligent protection, precise selective protection and avoiding unnecessary power stop.

It is equipped with open and communicative interface so as to satisfy the requirement of controlling center and automatic system.

This type of air circuit breaker withstands voltage 8000V in the altitude of 2000M (different altitude applies to different standard, at most 12000V).
