FXD63B250 - 250Amp Circuit Breaker Description
FXD63B250 - 250Amp Circuit Breaker
The Siemens FXD63B250 is a 250 Amp, 3-pole molded case circuit breaker from the Sentron FD series, built for use in compatible Siemens low-voltage electrical distribution equipment. It uses a thermal magnetic trip unit with a fixed, non-interchangeable trip and is rated for systems up to 600VAC.
If you're replacing an existing FD-frame breaker, the FXD63B250 is designed to match the original installation without changing the electrical layout. This version is supplied without factory-installed lugs, making it suitable for applications where compatible field-installed terminals are required.
