BF120H - 20Amp Circuit Breaker

BF120H - 20 Amp Circuit Breaker

The BF120H circuit breaker 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 BLHF frame type, this breaker provides a 22kA A.I.C. interrupting rating at 120VAC, making it suitable for applications where higher available fault current must be safely managed. HACR rated and calibrated for 40°C operation, the BF120H is commonly used in commercial and light industrial panelboards requiring a secure bolt-on connection. It is engineered for proper form, fit, and function in compatible legacy electrical systems and panel configurations. Constructed for durability and long service life, this breaker helps protect conductors and equipment from overloads and short circuits while maintaining code-compliant performance.
