FA24050BC - 50 Amp Circuit Breaker

FA24050BC - 50 Amp Circuit Breaker

When you need a compatible replacement for an existing FA-frame I-Line electrical system, the FA24050BC is designed to provide the same form, fit, and function as the original equipment. This 50 Amp, 2-pole molded case circuit breaker uses a thermal-magnetic trip mechanism that responds to overloads and short circuits, helping protect electrical circuits and connected equipment during normal operation. Designed for 60Hz applications, this breaker features an I-Line plug-in connection with a B-C phase configuration, making it suitable for compatible panelboards and switchboards without requiring changes to the existing installation.
