A2D35R - 35 Amp Fuse

A2D35R - 35 Amp Fuse

When your electrical systems are pushed hard, reliable circuit protection becomes essential. The Mersen A2D35R Amp-Trap 2000® Class RK1 Time-Delay Fuse is built to help keep industrial and commercial equipment running safely while reducing the risk of costly downtime and component damage. Rated at 35 amps and designed for both 250VAC and 250VDC applications, this high-performance fuse combines fast short-circuit protection with the time-delay capability needed to handle normal motor start-up surges without unnecessary interruptions.

What makes the A2D35R especially valuable in motor-driven systems is its ability to react quickly during dangerous fault conditions while still tolerating temporary in-rush currents common in HVAC systems, pumps, conveyors, compressors, and industrial machinery. That balance helps you protect starters, switches, contactors, and other sensitive electrical components from damage caused by severe overcurrent events. The built-in SmartSpot® blown fuse indicator also makes maintenance easier by providing a clear visual indication when the fuse has operated, helping technicians troubleshoot faster and minimize downtime.
