BQCH3B050 - 50Amp Circuit Breaker

BQCH3B050 - 50Amp Circuit Breaker

When you need a 50 amp, 3-pole circuit breaker that matches the specifications of an existing installation, the BQCH3B050 delivers the form, fit, and functionality required for many commercial and industrial electrical systems. Designed with a BQCH frame and bolt-on mounting configuration, this molded case circuit breaker helps provide dependable circuit protection against overloads and short circuits while fitting compatible equipment as intended.

The BQCH3B050 is commonly found in three-phase power distribution systems where maintaining compatibility with existing panelboards and electrical equipment is essential. Its 50 amp rating makes it suitable for a variety of branch circuit and equipment protection applications, while the 14kA interrupting rating at 480VAC supports installations that require this level of fault-current protection. Because it is HACR rated, it is frequently used with heating, ventilation, air conditioning, and refrigeration equipment found throughout commercial facilities.

Whether you're maintaining a manufacturing plant, servicing a commercial building, or replacing a breaker in an established electrical distribution system, choosing the correct frame type, pole configuration, and mounting style can save time and help keep projects moving. Built to last, the BQCH3B050 is designed for applications where a 50 amp, 3-pole bolt-on molded case circuit breaker is required.
