BQCH2B020 - 20Amp Circuit Breaker

BQCH2B020 - 20 Amp Circuit Breaker

The BQCH2B020 is a 2-pole, 20-amp molded case circuit breaker designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built on the BQCH frame platform, this bolt-on breaker is engineered to provide consistent overcurrent protection in panelboards operating up to 480VAC, with an interrupting capacity of 14kA at 480VAC. Rated for 40°C environments and HACR applications, the BQCH2B020 is well-suited for HVAC equipment circuits and other branch circuit protection needs. Its bolt-on mounting configuration ensures a secure, stable connection within compatible panelboards, helping maintain proper contact and alignment over time. Designed for long service life and reliable operation, this breaker is intended as a form, fit, and functional replacement within existing electrical systems that require a BQCH frame, 20A, 2-pole configuration.
