BQCH1B015 - 15Amp Circuit Breaker

BQCH1B015 - 15 Amp Circuit Breaker

The BQCH1B015 circuit breaker is a 1-pole, 15-amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial panelboards that require a BQCH frame type. Rated at 14k A.I.C. at 277VAC, this bolt-on breaker helps protect branch circuits from overloads and short circuits while maintaining proper coordination within compatible electrical distribution systems. Built for operation in 40°C ambient conditions and carrying an HACR rating, the BQCH1B015 is well-suited for HVAC-related applications and other equipment requiring consistent, code-aligned protection. Its compact dimensions and bolt-on mounting style ensure proper fit and secure installation in designated panelboards using the BQCH platform. Like other molded case breakers in its class, it is built to last and designed to provide reliable circuit protection when properly installed and maintained.
