Why Choose the Mersen A4J35 Amp-Trap Fuse?
The Mersen A4J35 is a premium Class J fast-acting current-limiting fuse designed to provide dependable protection against overloads and short circuits in industrial and commercial electrical systems. As part of the proven Mersen Amp-Trap A4J series, it delivers exceptional current-limiting performance while helping minimise equipment damage and system downtime.
Designed for demanding industrial applications, the A4J35 rapidly interrupts fault currents before they reach damaging levels, reducing thermal and mechanical stress on downstream electrical equipment. Its unique Class J rejection dimensions prevent substitution with lower-rated fuse classes, helping maintain system safety and compliance.
With a rated current of 35 A, a 600 V AC rating and a 300 V DC rating, the Mersen A4J35 is ideal for protecting feeders, branch circuits, panelboards, switchboards and general industrial loads requiring fast-acting overcurrent protection.
