CHB315 - 15Amp Circuit Breaker

CHB315 - 15 Amp Circuit Breaker

The CHB315 circuit breaker is a 3-pole, 15-amp bolt-on breaker built for use in CHB frame panelboards and distribution equipment operating at up to 240VAC. Designed for dependable overcurrent protection in commercial and light industrial electrical systems, this breaker provides 10kA A.I.C. interrupting capacity at 240VAC, helping safeguard branch circuits against overloads and short circuits. Its bolt-on mounting style ensures a secure, stable connection to the panelboard bus, making it a practical form, fit, and functional replacement for compatible CHB frame installations. Built to last and engineered for consistent operation within its rated capacity, the CHB315 is well suited for maintaining existing electrical infrastructure where matching specifications and footprint are critical.
