Mersen AG Class G Time Delay Fuse, 480VAC, Ferrule Terminal

Mersen AG40 Class G Time Delay Fuse, 40A 480VAC

The Mersen AG40 Class G Time Delay Fuse delivers reliable 40A overcurrent protection at 480VAC using advanced Amp-Trap technology. This ferrule-terminal fuse features tin-plated copper connection terminals and a GMG body insulating material for dependable performance in commercial and industrial applications, with a 100 kA breaking capacity for high-energy fault interruption. The time delay characteristic allows temporary overloads for motor starting while still clearing sustained faults and short circuits quickly.
