Why Choose the Mersen AJT1N Class J Time-Delay Fuse?
The Mersen AJT1N is a premium Class J time-delay fuse engineered to provide reliable overcurrent protection for industrial and commercial electrical systems. As part of the trusted Amp-Trap 2000® AJT series, it delivers outstanding current-limiting performance while accommodating temporary motor-starting and transformer inrush currents without unnecessary fuse operation.
Designed for demanding branch circuit applications, the AJT1N protects motors, transformers, control panels and electrical distribution equipment from damaging overloads and short circuits. Its compact Class J design requires significantly less mounting space than comparable Class RK fuses, making it ideal for modern control panels and switchgear installations.
With a rated current of 1 A and voltage ratings of 600 V AC / 500 V DC, the AJT1N is suitable for industrial automation systems, OEM machinery, HVAC equipment and power distribution applications. The N suffix identifies this version as the non-indicating model, designed for installations where a visual blown-fuse indicator is not required.

Reliable Protection for Industrial Electrical Systems
The AJT series combines time-delay performance with advanced current limitation, allowing temporary inrush currents from motors and transformers to pass while rapidly interrupting sustained overloads and short-circuit faults. This helps maximise equipment uptime and reduces nuisance fuse replacement.
Its high interrupting capacity and compact construction make the AJT1N an excellent choice for protecting sensitive electrical equipment in industrial control panels, machinery and power distribution systems where dependable overcurrent protection is essential.
