FD63B250L - 250Amp Circuit Breaker Description
FD63B250L - 250Amp Circuit Breaker
The FD63B250L Siemens circuit breaker is a 250 Amp, 3-pole molded case circuit breaker built for electrical systems that need dependable protection and reliable performance. As part of the Siemens SENTRON FD frame family, this breaker is designed for commercial and industrial applications where protecting equipment, feeders, and distribution systems from overloads and short circuits is critical.
When you need a 600V circuit breaker with higher amperage capacity, the FD63B250L provides a practical solution with its thermal magnetic trip unit, which responds to both long-term overload conditions and sudden short-circuit events.
