Why Choose the Mersen AJT6-1/4N Class J Fuse?
The Mersen AJT6-1/4N is a high-performance 6.25 A Class J time-delay fuse designed to provide dependable overcurrent and short-circuit protection for industrial electrical equipment. As part of the renowned Mersen Amp-Trap 2000 AJT series, this current-limiting fuse combines strong fault protection with the ability to withstand temporary motor-starting and transformer inrush currents.
Its time-delay operating characteristic helps prevent unnecessary fuse operation during normal transient conditions while responding rapidly to hazardous overcurrents. This makes the AJT6-1/4N suitable for protecting motors, transformers, control panels, branch circuits and other industrial loads where both overload tolerance and effective fault interruption are required.
With a current rating of 6.25 A and a voltage rating of up to 600 V AC, the Mersen AJT6-1/4N supports a wide range of industrial power distribution and machinery applications. Its compact Class J body provides high interrupting capacity while helping reduce the space required inside electrical enclosures.

Reliable Protection for Industrial Electrical Systems
The Mersen AJT6-1/4N protects electrical equipment by interrupting excessive current before conductors and connected components sustain serious thermal or mechanical damage. Its current-limiting action restricts the amount of fault energy that can pass through the circuit during a short circuit.
Unlike fast-acting fuses, the AJT series incorporates a time delay that tolerates temporary current surges associated with motor starting, transformer energisation and other normal operating events. This balance of overload tolerance and rapid short-circuit response makes it well suited to demanding industrial control and power distribution applications.
Typical Applications
- Industrial motor branch circuits.
- Transformers and control transformers.
- Machinery and automation control panels.
- Power distribution equipment.
- Heating and resistive-load circuits.
- Industrial lighting and branch-circuit protection.
