A6D25R - 25 Amp Fuse

A6D25R - 25 Amp Fuse

The A6D25R Amp-Trap 2000® fuse is made for your electrical systems that need reliable overcurrent protection without creating unnecessary interruptions. This 25A Class RK1 time-delay fuse helps protect your motors, branch circuits, feeders, and other electrical equipment from overloads and short circuits while still allowing temporary startup currents during normal operation. In day-to-day use, that means equipment can start normally without nuisance fuse openings slowing things down.

The A6D25R is designed to react quickly during serious fault conditions to help reduce damage to switches, motor starters, contactors, and connected components. At the same time, its time-delay performance helps handle the brief in-rush currents that are common with HVAC systems, pumps, compressors, and motor-driven equipment. That combination makes it a practical choice for commercial and industrial applications where keeping systems running matters.

Another helpful feature is the built-in SmartSpot® blown fuse indicator, which gives technicians a quick visual indication when the fuse has opened. That can make troubleshooting faster and help you reduce downtime during maintenance. The A6D25R is also commonly used as a replacement for older Class H, K, and RK5 fuses already installed in existing systems, making upgrades and routine replacements easier.
