A2D200R - 200 Amp Fuse

A2D200R - 200 Amp Fuse

In busy electrical systems, the last thing you want is unnecessary downtime caused by nuisance fuse openings or equipment damage during a fault. The Mersen A2D200R Amp-Trap 2000® fuse is built to help prevent those problems before they start. Designed for industrial and commercial applications, this 200A Class RK1 time-delay fuse provides reliable overcurrent protection for motors, feeders, branch circuits, and other critical equipment without interfering with normal startup currents.

Mersen also includes its SmartSpot® indicator, which makes identifying a blown fuse much quicker during maintenance or troubleshooting. Instead of spending extra time testing fuses one by one, technicians can quickly spot the issue and get systems back online faster. For facilities running manufacturing equipment, HVAC systems, pumps, or heavy-duty machinery, that can make a real difference in reducing downtime.
