Product Spec Sheet
Amp-Trap 2000 time-delay A2D-R fuses provide IEC Type 2 "no damage" protection to existing mains, feeders, and branch circuits serving motor and non-motor loads. A2D-R fuses will open fast enough under extreme fault conditions for maximum short circuit protection to prevent damage to motor starters, switches, and other circuit components, yet also provide the time-delay needed for motor in-rush currents. A2D-R fuses can be used to replace older 250V Class H, K or RK5 fuses already installed in the field.
