CHB350 - 50Amp Circuit Breaker

CHB350 - 50 Amp Circuit Breaker

The CHB350 circuit breaker is a 3-pole, 50-amp bolt-on breaker designed for use in electrical distribution systems requiring dependable overcurrent protection at up to 240VAC. Built within the CHB frame type, this breaker is intended for installations where a secure bolt-on connection is required to maintain a stable electrical interface with compatible panelboards. With a 10kA A.I.C. interrupting rating, the CHB350 helps protect circuits and equipment by interrupting fault currents within its rated capacity. Its three-pole configuration makes it suitable for managing multi-phase circuits commonly found in commercial and industrial electrical panels. The compact design allows it to fit properly into panelboards designed for CHB frame breakers, helping ensure proper form, fit, and function when replacing an existing unit in compatible systems. Like many electrical components designed for long service life, this breaker is built to last and supports safe operation in legacy power distribution environments when installed according to applicable electrical standards.
