Westinghouse Cutler-Hammer FB2050 Circuit Breaker

Westinghouse Cutler-Hammer FB2050 is a 2-pole, 50-amp circuit breaker rated for 600 VAC. As part of the Type FB family, it is designed to interrupt fault currents and protect electrical circuits by opening the circuit when an overload or short circuit is detected. The 2-pole design disconnects both live conductors simultaneously, which is important for safely interrupting two-line or multi-wire circuits and maintaining system safety. With a 50 A rating and a 600 VAC maximum, this FB-series breaker provides reliable overcurrent protection for circuits in panels that operate at higher voltages. The FB2050 designation identifies the exact current rating and series within the Westinghouse Cutler-Hammer lineup, helping ensure correct replacement and matching with existing installations. When selecting a unit, confirm that the current and voltage ratings match the protected circuit's requirements to prevent nuisance trips or insufficient protection. This device serves to protect electrical infrastructure by interrupting current in the event of overloads or faults, contributing to safer and more reliable operation of the electrical system.
