Mersen GTL30 30A 125V Time-Delay Plug Fuse

The Mersen GTL30 is a 30-amp, 125V AC time-delay plug fuse built for dependable overcurrent protection in both residential and industrial settings. Featuring a glass body, brass contacts, and a screw-in Edison base, it installs easily into any standard Edison base fuse panel or holder — no tools, no hassle.
The time-delay characteristic is what sets the GTL30 apart for motor load applications. It tolerates the momentary inrush current that occurs when motors start up, preventing unnecessary tripping while still responding decisively to genuine overloads and short circuit faults. With a 10kA AC interrupting rating, it's rated to safely clear even high-magnitude fault currents before damage can occur downstream.
At 30 amps, this is the highest current rating in the GTL series, making it the right choice for larger motor loads, heavier branch circuits, and applications where a 20-amp fuse just doesn't cut it. UL listed and CSA certified, it meets safety requirements for both U.S. and Canadian markets.
Sold in boxes of 4, the GTL30 is a reliable, code-compliant replacement or upgrade for aging fuse-protected panels in workshops, light manufacturing, HVAC systems, and residential service panels.
