Size: 5 Inch Length x 0.810 Inch Width
Inventory consolidation of class rk1, rk5 and h fuses for reduced sku investment and minimizing potential for misapplying fuse
"No damage" "Type 2" protection for IEC and NEMA starters when properly sized
Bussmann Low-Peak® Class RK1 Dual-element current limiting time-delay fuse has current rating of 1/2 Amps and rms symmetrical interrupt rating of 300 kilo-Amps at 600 VAC/100 kilo-Amps at 100 VDC. It has ferrule terminal for connection. Fuse has time-delay that permits 130% FLA sizing for back-up motor protection and single-phase motor damage. It measures 5 Inch x 0.810 Inch. Fuse offers lower power loss that reduces the power consumption and high in-rush current motor protection. It is ideal for large distribution switchboards, power panel boards, motor control centers, machinery disconnect switches.
Fuse has diameter of 0.81 Inch and electrically isolated end caps for added safety. Separate overload and short-circuit elements provide time delay for sizing of high inrush loads linked with rk1 current-limitation. Selective coordination ratio of 2:1 prevents electrical shutdowns from extending beyond the failed circuit. Fuse is UL, CSA listed.
