Why Choose the Mersen AJT3N Class J Time-Delay Fuse?
The Mersen AJT3N is a compact and dependable Class J time-delay fuse designed to protect industrial electrical systems against overloads and short circuits. As part of the established Mersen Amp-Trap 2000® AJT series, it combines effective current-limiting performance with time-delay characteristics, making it suitable for circuits containing motors, transformers and other equipment that generate temporary inrush currents.
The AJT3N is engineered to withstand normal start-up surges while responding reliably to sustained overcurrent conditions. Its compact Class J format helps reduce panel-space requirements compared with larger fuse classes, making it a practical choice for control-panel builders, machine manufacturers and industrial maintenance applications.
With a rated current of 3 A and a 600 V AC / 500 V DC rating, the AJT3N is suitable for industrial control circuits, transformer protection, motor branch circuits and general power distribution. Its ferrule-style construction supports straightforward installation in compatible Class J fuse holders and fused disconnect equipment.

Reliable Protection for Industrial Electrical Systems
The Mersen AJT3N interrupts sustained overload and short-circuit currents before excessive fault energy can damage conductors, controls and connected equipment. Its time-delay response allows normal temporary surges associated with motor starting and transformer energisation to pass without unnecessary fuse operation.
Its current-limiting characteristics help reduce thermal and mechanical stress during fault conditions. This makes the AJT3N a dependable solution for industrial machinery, control panels and electrical distribution equipment where reliable protection and efficient use of installation space are important.
Typical Applications
- Industrial control panels.
- Motor branch circuit protection.
- Transformer primary and secondary circuits.
- OEM machinery and automation equipment.
- Feeder and branch circuit protection.
- General industrial power distribution systems.
