QF250 - 50Amp Circuit Breaker

QF250 - 50Amp Circuit Breaker

The QF250 is a 2-pole, 50-amp Type QPF plug-on circuit breaker designed to provide both overcurrent protection and Class A Ground-Fault Circuit Interrupter (GFCI) protection for your 120/240 VAC electrical systems. Featuring a 10kA interrupting rating and a 5mA Class A ground-fault trip threshold, this breaker helps you protect people from electrical shock by quickly interrupting the circuit when a ground fault is detected. Its plug-on design allows for straightforward installation in compatible load centers and panelboards, making it a practical form, fit, and functional replacement for maintaining your existing electrical distribution systems. Built to last and HACR-rated, the QF250 is well-suited for applications where dependable circuit and ground-fault protection are required.
