AJT1 - 1 Amp Fuse

AJT1 - 1 Amp Fuse

The AJT1 Class J fuse is built for your electrical systems that need dependable protection without taking up unnecessary space inside a panel. Rated at 1 amp with a 200 kA interrupting capacity at 600 VAC, this time-delay fuse is designed to help protect circuits from overloads and short circuits while still handling the brief startup surges common in many industrial and commercial applications.

What makes the AJT1 especially useful is its balance of protection and practicality. The time-delay design helps reduce nuisance openings caused by temporary inrush currents, which can help keep your equipment running smoothly and cut down on avoidable maintenance interruptions. Its compact cartridge-style construction also makes it a solid fit for tighter installations where every inch inside the enclosure counts.

For electricians, maintenance crews, and facility operators replacing a Class J fuse, the AJT1 offers a straightforward solution that’s easy to integrate into existing systems. Whether you're using it in control panels, machinery, or distribution equipment, this fuse is designed to deliver consistent performance where reliable circuit protection matters most.
