Mersen AJT3-1/2 Amp-Trap 2000 Class J Time-Delay Fuse, 3.5A 600V (Lot of 8)

This lot includes eight (8) high-performance AJT3-1/2 (3.5 Amp) Class J fuses manufactured by Mersen (formerly Ferraz Shawmut). As part of the Amp-Trap 2000® series, these fuses are engineered to provide "No Damage" IEC Type 2 protection for main, feeder, and branch circuits.

Key Features:

Time-Delay Function: Specifically designed to handle the high inrush currents typical of motor starting and transformer applications without nuisance tripping.

Current-Limiting: Offers superior current-limiting ability, significantly reducing the peak let-thru current during a fault to protect downstream components.

Compact Design: Requires only half the mounting space of standard 600V Class RK fuses, allowing for smaller and more economical fuse blocks.

High Interrupting Rating: Features a robust 200kA interrupting rating at 600VAC (self-certified up to 300kA).

Durable Construction: Built with a fiberglass body for dimensional stability in harsh industrial environments and high-grade silica filler for fast arc quenching.

Specifications (per fuse):

Amperage Rating: 3.5 Amps.

Voltage Rating: 600VAC / 500VDC.

Fuse Class: Class J.

Dimensions: Approximately 0.81" Diameter x 2.25" Length.

Standards: UL Listed to Standard 248-8 and CSA Certified.

Applications: Ideal for motor circuits, mains, feeders, transformers, control panels, and load centers.
