Why Choose the Mersen AJT35 Class J Time-Delay Fuse?
The Mersen AJT35 is a high-performance Class J time-delay fuse designed to provide dependable overcurrent protection for industrial electrical systems. 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 subject to temporary inrush currents.
The AJT35 is engineered to minimise damage caused by sustained overloads and short circuits while reducing unnecessary fuse operation during normal equipment start-up. Its compact Class J construction occupies less panel space than many comparable fuse formats, helping panel builders and OEM manufacturers create efficient electrical assemblies without compromising circuit protection.
With a rated current of 35 A and a 600 V AC / 400 V DC rating, the AJT35 is ideal for motor branch circuits, industrial machinery, transformers, feeders and power distribution equipment. Its blade-style terminals allow secure installation in compatible Class J fuse holders, fuse clips and fused disconnect switches.

Reliable Protection for Industrial Electrical Systems
The Mersen AJT35 protects connected equipment by interrupting dangerous overload and short-circuit currents before they can cause extensive thermal or mechanical damage. Its time-delay response allows normal temporary surges associated with motor starting and transformer energisation to pass without unnecessary fuse replacement.
Its current-limiting performance helps reduce the amount of fault energy delivered to downstream equipment. This makes the AJT35 a practical choice for industrial control panels, production machinery and electrical distribution systems where reliable protection, system uptime and space efficiency are important.
