AJT125 – Mersen | CLASS J TD 600V 125A

Description

The Mersen AJT125 is a 600V, 125A Class J time-delay fuse from the Amp-Trap 2000® series. Engineered with advanced materials, this fuse provides IEC Type 2 No Damage protection for a variety of circuits, including motors, feeders, and transformers. Its compact design requires half the mounting space of typical 600VAC Class RK fuses. The AJT fuse’s time-delay characteristic is ideal for motor and transformer inrush currents while offering superior current-limiting capability.
