Ferraz Shawmut Amp-Trap® 2000® SmartSpot® A6D50R Time Delay Fuse, 50 A, 600 VAC/VDC, 200 kA at 600 VAC, 100 kA at 600 VDC Interrupt, Class: RK1, Poly Tube Body

Amp-Trap® 2000® SmartSpot time delay A6D-R fuses provide IEC Type 2 "no damage" protection to existing mains, feeders and branch circuits serving motor and non-motor loads. A6D-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. A6D-R fuses can be used to replace older 600 V Class H, K or RK5 fuses already installed in the field.
