BQCH1B030 - 30Amp Circuit Breaker

BQCH1B030 - 30 Amp Circuit Breaker

The BQCH1B030 is a 1-pole, 30-amp molded case circuit breaker designed for reliable overcurrent protection in commercial and industrial panelboard applications. Built on the BQCH frame, this bolt-on breaker delivers a 14k A.I.C. rating at 277VAC, helping protect branch circuits from overloads and short circuits in demanding electrical systems. HACR rated and calibrated for 40°C environments, the BQCH1B030 is engineered for consistent operation under typical field conditions. Its bolt-on mounting configuration provides secure installation and dependable electrical contact, making it a practical solution for maintaining or servicing compatible panelboards. Like other molded case breakers in its class, it is built to last and designed for long-term service when properly installed and maintained.

If you’re replacing an existing BQCH frame breaker, this model is intended to match the original form, fit, and function—ensuring proper compatibility with approved equipment and preserving system integrity.
