BQCH2B050 - 50Amp Circuit Breaker

BQCH2B050 - 50Amp Circuit Breaker

If you're searching for a BQCH2B050, chances are you're looking for a breaker that matches what's already installed. This 50 amp, 2-pole bolt-on molded case circuit breaker is designed for systems that use a BQCH frame and require a 14kA interrupting rating at 480VAC. When replacing electrical components, matching the original ratings and mounting style helps keep the system configured the way it was designed.

The BQCH2B050 is commonly found in commercial and industrial equipment, including panelboards, HVAC systems, refrigeration equipment, motor circuits, and other power distribution applications. Its bolt-on design allows it to be securely mounted in compatible equipment, while the 2-pole configuration is used where both poles must disconnect together.

Because this breaker is HACR rated, it can be used in heating, air conditioning, and refrigeration applications where that rating is required. It's also rated for 40°C ambient conditions, making it suitable for many everyday operating environments. Whether you're replacing a breaker that has failed or simply matching an existing installation, the BQCH2B050 provides the ratings and configuration needed for a compatible replacement. Like many breakers built for commercial and industrial service, it's designed to hold up over time when used within its intended specifications.
