Class-RK5 fuses are designed for moderate current limiting applications and disconnecting circuits before getting exposed to the sustained loads and short-circuit conditions. Raptor Supplies offers a wide range of these products from brands like Ferazz Shawmut and Bussmann featuring rejection clips in fuse holders for preventing the installation of other fuses with lower interrupting capacities. Bussmann Class RK5 fuses feature a time delay mechanism for protecting against temporary motor overload and inrush currents with a minimum delay of 10 seconds at 500 per cent of ampere rating. These units allow selective coordination to eliminate the occurrence of blackouts and help protect the downstream components against damaging thermal and magnetic effects of faulty electric currents. Ferraz Shawmut Class RK5 fuses feature a fibreglass encapsulation for dimensional stability in harsh conditions. These 600 VDC rated fuses feature a dual element and are ideal for use with feeders, branch circuits, transformers and service entrance equipment.
