Mersen GW10 10A 125V Fast-Acting Plug Fuse

The Mersen GW10 is a 10-amp, 125V AC fast-acting plug fuse designed for receptacle and lighting circuit protection in both residential and industrial applications. With a glass body, brass contacts, and a standard screw-in Edison base, it drops right into any compatible fuse panel for quick, straightforward installation.
Unlike time-delay fuses, the GW10 is built to respond immediately to overcurrent conditions — making it the right choice for circuits where there's no expected inrush current and fast fault clearing is the priority. Lighting circuits, receptacle branch circuits, and sensitive equipment that can't tolerate prolonged overcurrent exposure are all ideal use cases.
A standout feature of the GW10 is its built-in visual blown fuse indicator, which lets you quickly identify a blown fuse at a glance without pulling and testing each one individually — a real time-saver in troubleshooting scenarios. With a 10kA AC interrupting rating, it handles high fault currents safely and reliably.
UL listed and approved for North American use, the GW10 is a dependable, code-compliant choice for protecting lighting and receptacle circuits in homes, commercial buildings, and light industrial facilities.
