QCHGFT2040 - 40 Amp, GFCI (5mA) Circuit Breaker

QCHGFT2040 - 40 Amp, GFCI (5mA) Circuit Breaker

If you’re looking for a circuit breaker that does more than just “trip,” the QCHGFT2040 40 Amp 2-pole GFCI circuit breaker is built to protect both your electrical system and the people using it. This isn’t just about keeping circuits running—it’s about adding an extra layer of safety where it counts most. With built-in 5mA ground fault protection, this breaker helps detect even small electrical leaks that could pose a shock hazard. That makes it a smart choice for areas where water and electricity might meet—like kitchens, bathrooms, garages, or outdoor setups. Pair that with a thermal magnetic trip system, and you’ve got fast, reliable protection against overloads and short circuits without overcomplicating your install. Its 22kA interrupting rating at 120/240 VAC means it’s ready to handle serious fault conditions, while the feed-thru design keeps downstream circuits powered efficiently. In short, it’s a dependable, no-nonsense solution for professionals who want safety, performance, and ease of use in one breaker.
