Why Choose the Mersen AJT5-6/10N Class J Time-Delay Fuse?
The Mersen AJT5-6/10N is a premium Class J time-delay fuse engineered to provide dependable overcurrent protection for industrial electrical systems. As part of the trusted Mersen Amp-Trap 2000® AJT series, it combines exceptional current-limiting performance with time-delay characteristics, making it ideal for protecting motors, transformers, control panels and branch circuits where temporary inrush currents are expected.
Manufactured using advanced fuse technology, the AJT5-6/10N tolerates temporary motor-starting and transformer energisation currents while rapidly interrupting sustained overloads and short circuits. Its compact Class J design occupies approximately half the mounting space required by comparable Class RK fuses, enabling more efficient panel layouts without sacrificing protection.
With a 5.6 A current rating and a 600 V AC / 500 V DC rating, the AJT5-6/10N is ideally suited for industrial control panels, OEM machinery, motor branch circuits and transformer protection. Its ferrule construction provides secure installation in compatible Class J fuse holders and disconnect switches.
