A2D15R - 15 Amp Fuse

A2D15R - 15 Amp Fuse

The Mersen A2D15R Amp-Trap 2000® fuse is made for electrical systems that need dependable protection day after day. Rated at 15 amps, this Class RK1 time-delay fuse helps you protect motors, feeders, branch circuits, and other equipment from overloads and short circuits without creating unnecessary interruptions during startup.

Electrical equipment often pulls extra current for a brief moment when powering on. Standard fuses can sometimes react too quickly and open even when the equipment is operating normally. The A2D15R is designed to handle those short startup surges while still clearing dangerous fault conditions fast enough to help protect connected equipment.

The built-in SmartSpot® indicator also makes your maintenance easier. When the fuse opens, the indicator gives maintenance personnel a quick visual reference, helping reduce troubleshooting time and speed up replacement. Its ferrule-style design installs easily in compatible fuse clips and control equipment commonly found in industrial and commercial systems.

The A2D15R is frequently used in motor control centers, HVAC equipment, manufacturing systems, and commercial electrical panels where reliable circuit protection is important. It can also replace older Class H, K, and RK5 fuses already installed in existing systems.
