FA24050BC **Old Style** - 50 Amp Circuit Breaker

FA24050BC **Old Style** - 50 Amp Circuit Breaker

If you're maintaining an existing I-Line electrical distribution system, the FA24050BC Old Style provides a compatible 50 Amp, 2-pole thermal-magnetic molded case circuit breaker for applications that require this specific configuration. Built for I-Line plug-in installation with a B-C phase arrangement, this breaker is intended to match the original equipment's form, fit, and function, making it a practical choice when replacing a breaker in an existing panelboard or switchboard. Its thermal-magnetic trip unit responds to both prolonged overloads and short-circuit faults, providing the circuit protection expected in commercial and industrial power distribution systems.
