Mersen A2D4R
Fuse A2D-R Time-Delay Class RK1 250V 4A
Product Description
The A2D-R time-delay fuse provides effective IEC Type 2 "no damage" protection for mains, feeders, and branch circuits that service motor and non-motor loads. This fuse is designed to open rapidly under severe fault conditions, offering optimal short circuit protection that safeguards motor starters, switches, and other circuit components.
Additionally, it incorporates a time-delay function to accommodate motor in-rush currents, making it a versatile choice for modern electrical systems. The A2D-R fuse can serve as a direct replacement for older 250V Class H, K, or RK5 fuses currently in use.
Specifications include a rated voltage of 250 V for both AC and DC, a breaking capacity of 200 kA, and compliance with ROHS standards. The fuse features a clip mounting style, with terminals made of tin-plated copper and an insulating body constructed from PolyTube material. The product measures 2 inches in length and 0.56 inches in diameter, weighing 0.04 lb.
