Introducing the Murray MP120GF — a 20A, 1-pole, 120V GFCI plug-on circuit breaker designed to protect circuits within panelboards, load centers, and electrical distribution networks. Built for retrofit projects and maintenance scenarios where the part number must stay consistent, this MP120GF ensures you can upgrade protection without reconfiguring your entire panel.
