Considerable CE cost savings occur by permitting the use of smaller size switches, panels, and fuses them- selves. Provides current limitation to help protect down- stream components from high fault currents. Gives motor running back-up protection to motors without extra costs.Technical Data 1017 Fusetron 600 V Class RK5 FRS-R 600 Vac/300 Vdc, Effective August 2018 1/10-60 A, dual element, time-delay fuses Time-current curves - average melt Recommended fuse blocks 1/10 to 8 amps Catalog no.
