Technical Data 1017 Effective May 2016 Supersedes August 2013 BUSSMANN SERIES Fusetron™ 600 V Class RK5, FRS-R — 600 Vac/300 Vdc, 1/10-60 A, dual element, time-delay fuses Catalog symbol: • FRS-R-(amp) (non-indicating) • FRS-R-(amp)ID (indicating) Description: • Advanced protection, energy efficient Class RK5 dual element, current-limiting, time-delay fuses with optional open fuse indication on select ratings • Time-delay – 10 second (minimum) at 500% of rated current Specifications: Ratings • Volts • 600 Vac, 300 Vdc (1/10-30 A) • 600 Vac, 250 Vdc (35-60 A) • Amps — 1/10-60 A • Interrupting rating • 200 kA Vac RMS Sym • • • • • • Offers a 10-second time delay at 5 times the rated current • The time-delay feature makes it possible to use fuse amp ratings that are much smaller than those of non-time delay fuses. Considerable cost savings occur by permitting the use of smaller size switches, panels, and fuses themselves. • Provides current limitation to help protect downstream components from high fault currents. • Gives motor running back-up protection to motors without extra costs.
