BF1B020 - 20Amp Circuit Breaker

BF1B020 - 20 Amp Circuit Breaker

The BF1B020 is a 1-pole, 20-amp bolt-on molded case circuit breaker designed for dependable circuit protection in 120VAC electrical distribution systems. Built on the BQF frame platform, this breaker features integrated Ground Fault Circuit Interruption (GFCI) to help protect personnel and equipment from ground fault conditions. With a 10kA interrupting rating at 120VAC and a bolt-on mounting configuration, the BF1B020 is engineered for secure installation in compatible panelboards. Rated for operation at 40°C, it is well-suited for commercial and industrial environments where consistent overcurrent and ground fault protection is required. Like many molded case breakers of its class, it is built to last and intended to provide reliable service in properly maintained electrical systems.

Whether you are maintaining an existing facility or replacing a breaker in a compatible BQF panelboard, the BF1B020 is designed to match original electrical specifications for form, fit, and function. Its bolt-on design ensures a stable connection to the bus, helping reduce the risk of loose connections in applications subject to vibration or frequent load cycling.
