Siemens / Murray MP120GF – 20A GFCI Miniature Circuit Breaker Crafted

Built to handle 20-amp branch circuits, this ground fault interrupter delivers critical 5mA shock prevention for residential environments. It installs into legacy Murray and Siemens panelboards, offering a seamless hardware match for older infrastructure. As a direct cross-reference for the QF120A, it restores full functionality to aging electrical systems. The device utilizes a pigtail neutral wire and features a 10kA short-circuit current rating.
