BF125AH - 25Amp Circuit Breaker

BF125AH - 25 Amp Circuit Breaker

When you’re dealing with circuits in places where people are close to the power—kitchens, bathrooms, garages—you don’t want to take chances. The BF125AH is designed for exactly that kind of job. It’s a 25 amp, single-pole GFCI circuit breaker that adds an extra layer of protection by watching for ground faults and cutting power fast when something isn’t right. Unlike a standard breaker that only reacts to overloads or short circuits, this one is also looking for tiny current leaks (as low as 5mA). That’s the kind of detail that helps prevent electrical shock. It’s the type of protection electricians rely on when code—and common sense—call for GFCI coverage. Installation is straightforward thanks to the bolt-on design, which keeps the breaker firmly in place once installed. And with a 22kA interrupting rating at 120VAC, it’s built to handle serious fault conditions without hesitation. It’s compact, dependable, and does exactly what you expect it to do—no drama.

Key Features and Benefits

• Trips on ground faults (5mA): to help protect people from shock
• 25 amp, single-pole setup: for standard branch circuits
• Handles both overloads and short circuits: with thermal magnetic protection
• Bolt-on mounting: for a secure, stable fit in the panel
• 22kA interrupting capacity: for higher fault protection
• Slim profile: makes it easier to work within tighter panel spaces
