Why Choose the Mersen AJT1N Class J Time-Delay Fuse?
The Mersen AJT1N is a premium Class J time-delay fuse engineered to provide reliable overcurrent protection for industrial and commercial electrical systems. As part of the trusted Amp-Trap 2000® AJT series, it delivers outstanding current-limiting performance while accommodating temporary motor-starting and transformer inrush currents without unnecessary fuse operation.
Designed for demanding branch circuit applications, the AJT1N protects motors, transformers, control panels and electrical distribution equipment from damaging overloads and short circuits. Its compact Class J design requires significantly less mounting space than comparable Class RK fuses, making it ideal for modern control panels and switchgear installations.
With a rated current of 1 A and voltage ratings of 600 V AC / 500 V DC, the AJT1N is suitable for industrial automation systems, OEM machinery, HVAC equipment and power distribution applications. The N suffix identifies this version as the non-indicating model, designed for installations where a visual blown-fuse indicator is not required.
Key Advantages
- Compact Class J time-delay fuse for industrial branch circuit protection.
- 1 A current rating for low-current electrical applications.
- 600 V AC / 500 V DC voltage rating.
- Time-delay characteristics tolerate motor and transformer inrush currents.
