Why Choose the Mersen AJT2-8/10N Class J Time-Delay Fuse?
The Mersen AJT2-8/10N is a compact Class J time-delay fuse designed to provide reliable overcurrent protection for industrial and commercial electrical systems. Part of the proven Amp-Trap 2000® AJT series, it combines current-limiting performance with a controlled time delay that accommodates temporary motor-starting and transformer inrush currents.
Engineered for low-current branch circuits and control applications, the AJT2-8/10N helps protect motors, transformers, control panels and industrial equipment against sustained overloads and short circuits. Its compact Class J construction supports space-efficient panel layouts while delivering high fault-interruption capability.
With a rated current of 2.8 A and voltage ratings of up to 600 V AC and 500 V DC, the AJT2-8/10N is suitable for industrial automation, HVAC equipment, OEM machinery and electrical distribution systems. The N suffix identifies this model as a non-indicating fuse without a visual open-fuse indicator.

Reliable Protection for Industrial Electrical Systems
The AJT2-8/10N is designed to tolerate temporary current surges generated when motors start or transformers are energised. This controlled time-delay response helps reduce nuisance fuse operation while maintaining dependable protection against sustained overload conditions.
During a severe short circuit, the fuse limits the peak current and fault energy passed to downstream equipment. This helps reduce thermal and mechanical stress on conductors, contactors, control components and connected machinery, supporting improved electrical safety and system reliability.
