BQ1-C015 - 15Amp Circuit Breaker

BQ1-C015 - 15 Amp Circuit Breaker

The BQ1-C015 is a 1-pole, 15-amp molded case circuit breaker designed for use in 277VAC electrical distribution systems. Built on the BQ-C frame, this bolt-on breaker is commonly used in commercial panelboards where secure mounting and dependable branch circuit protection are required. It helps protect wiring and connected equipment from overloads and short circuits, supporting safe operation within existing electrical systems. With its bolt-on design, the BQ1-C015 provides a firm, stable connection to compatible panelboards. This style of mounting is often preferred in commercial and light industrial environments where equipment must remain securely fastened. Rated for operation at 40°C, it is intended for standard ambient conditions found in most electrical rooms and distribution areas. The molded case enclosure helps shield internal components and is built for long-term service in properly maintained systems. This breaker is designed specifically for proper form, fit, and function in applications that call for a BQ-C frame, 15 amp, single-pole configuration. It is suitable for maintaining and servicing existing installations that require these exact specifications.
