BQCH1B070 - 70Amp Circuit Breaker

BQCH1B070 - 70 Amp Circuit Breaker

The BQCH1B070 circuit breaker is a 70-amp, single-pole, bolt-on molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial distribution panels. Built on the BQCH frame platform, this breaker is rated for 14kA interrupting capacity at 277VAC, making it suitable for branch circuit protection where higher fault current ratings are required. Engineered for use at 40°C and HACR rated, the BQCH1B070 is commonly used in HVAC applications and other systems where consistent, code-compliant circuit protection is essential. Designed to provide proper form, fit, and function in compatible panelboards, this breaker helps maintain the integrity of existing electrical infrastructure while delivering the protection your system demands. With its bolt-on mounting configuration, the BQCH1B070 ensures a secure mechanical and electrical connection to the bus bar, reducing the risk of loose connections in high-demand environments. Whether you’re servicing a commercial facility, maintaining an industrial property, or replacing a breaker in a compatible panelboard, this unit is built to last and perform as intended within its specified ratings.
