FXD63B250L - 250Amp Circuit Breaker Description
FXD63B250L - 250Amp Circuit Breaker
The Siemens FXD63B250L is a 250 Amp, 3-pole molded case circuit breaker from the Sentron FD family, intended for compatible Siemens low-voltage distribution equipment. It uses a fixed, non-interchangeable thermal magnetic trip and is rated for systems up to 600VAC. Interrupting capacity is 22kAIC at 600VAC and 35kAIC at 480VAC, which is the key information to match when you're replacing an existing FD-frame breaker in a feeder or branch-circuit application.
