BF125A - 25Amp Circuit Breaker

BF125A - 25Amp Circuit Breaker

The BF125A circuit breaker is a 25 amp, single-pole, bolt-on thermal magnetic breaker engineered to deliver dependable overcurrent protection and integrated ground fault protection for personnel safety. Designed with a BLF frame type and rated at 10k A.I.C. at 120VAC, this breaker helps safeguard branch circuits from overloads and short circuits while its built-in 5mA Ground Fault Circuit Interrupter (GFCI) function provides critical protection against electrical shock. Ideal for applications where both circuit protection and code-compliant personnel safety are required, the BF125A offers consistent performance in commercial and light industrial electrical systems. Its bolt-on configuration ensures a secure, stable installation in compatible panelboards, reducing the risk of loose connections and enhancing overall system reliability. Built for electricians, facility managers, and contractors who demand dependable protection, the BF125A combines precise thermal magnetic trip response with sensitive ground fault detection. Whether you’re upgrading an existing panel or replacing a faulty breaker, this unit is designed to help maintain system integrity and minimize downtime.
