Why Choose the Mersen AJT60 Class J Time-Delay Fuse?
The Mersen AJT60 is a premium Class J time-delay fuse engineered to provide dependable overcurrent protection for industrial electrical systems. As part of the renowned Mersen Amp-Trap 2000® AJT series, it combines advanced current-limiting performance with time-delay characteristics, making it ideal for protecting motors, transformers, feeders and branch circuits where temporary inrush currents occur during normal operation.
Designed with advanced material technology, the AJT60 withstands normal motor-starting and transformer-energisation currents while rapidly clearing sustained overloads and short circuits. Its compact Class J construction requires approximately half the mounting space of comparable Class RK fuses, allowing more efficient panel layouts without compromising protection.
With a 60 A current rating and a 600 V AC / 400 V DC rating, the AJT60 is ideal for industrial control panels, motor branch circuits, transformer protection and power distribution equipment. The ferrule terminal design ensures secure installation in compatible Class J fuse holders and fused disconnect switches.
