Why Choose the Mersen AJT2-1/2N Class J Time-Delay Fuse?
The Mersen AJT2-1/2N is a premium Class J time-delay fuse engineered to provide dependable overcurrent protection for industrial and commercial electrical systems. As part of the trusted Amp-Trap 2000® AJT series, it combines advanced current-limiting technology with time-delay characteristics that allow temporary motor-starting and transformer inrush currents to pass without nuisance operation.
Designed for demanding branch circuit applications, the AJT2-1/2N protects motors, transformers, control panels and electrical distribution equipment against overloads and short circuits. Its compact Class J construction occupies approximately half the panel space required by comparable Class RK fuses while maintaining exceptional interrupting performance.
With a rated current of 2.5 A and voltage ratings of 600 V AC / 500 V DC, the AJT2-1/2N is ideal for industrial automation systems, OEM machinery, HVAC equipment and power distribution installations. The N suffix identifies this model as the non-indicating version, making it suitable where a visual blown-fuse indicator is not required.
