Why Choose the Mersen AJT8 Class J Fuse?
The Mersen AJT8 is a high-performance 8 A Class J time-delay fuse engineered to provide reliable overcurrent and short-circuit protection for industrial electrical systems. As part of the trusted Mersen Amp-Trap 2000 AJT series, it features advanced current-limiting technology and is designed to withstand the temporary inrush currents associated with motors, transformers and other inductive loads.
Its time-delay operating characteristic helps prevent nuisance fuse operation during normal equipment start-up while delivering rapid protection during fault conditions. The AJT8 is ideal for machinery, motor branch circuits, industrial control panels, transformers and power distribution equipment where dependable protection and maximum uptime are essential.
With a rated current of 8 A and voltage ratings of 600 V AC and 400 V DC, the AJT8 provides excellent protection in demanding industrial applications. Its compact Class J design requires significantly less mounting space than comparable Class RK fuses, making it an excellent choice for modern control panels.

Reliable Protection for Industrial Electrical Systems
The Mersen AJT8 protects industrial electrical equipment by interrupting excessive current before damage occurs to conductors and connected components. Its current-limiting design significantly reduces the amount of fault energy that passes through the circuit during a short circuit, helping extend equipment life.
The dual-element time-delay construction enables the fuse to withstand harmless temporary current surges while still providing rapid protection against genuine overloads and short circuits. This makes the AJT8 an excellent choice for industrial automation, machinery and power distribution applications.
Typical Applications
- Industrial motor branch circuits.
- Control panels and switchboards.
- Transformers and control transformers.
- Industrial machinery and automation equipment.
- Power distribution systems.
