QF250A - 50 Amp Circuit Breaker

QF250A - 50 Amp Circuit Breaker

The QF250A is a 2-pole, 50-amp Type QPF2 plug-on circuit breaker designed to provide dependable overcurrent protection while adding Class A Ground-Fault Circuit Interrupter (GFCI) protection for personnel safety. Rated for 120/240VAC applications with a 10kA interrupting capacity, this breaker helps you protect branch circuits from overloads, short circuits, and hazardous ground faults. Its 5mA Class A GFCI trip threshold is designed to quickly interrupt power when ground-fault conditions are detected, making it an excellent choice for installations where electrical codes require enhanced protection for people. With a convenient plug-on design for your compatible load centers and HACR rating, the QF250A offers a practical solution for residential and light commercial electrical systems requiring reliable circuit protection and code-compliant GFCI functionality.
