Carton quantity • • 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 • 20 kA Vdc • Dual-element feature provides the best timedelay performance, allowing closer sizing and superior protection of motors and transformers • Closer sizing allows for smaller fuses and less costly switches • Class RK5 fuses with a 200 kA interrupting rating for use in a broad range of applications • Provides motor overload, ground fault, and short-circuit protection • Helps protect motors against burnout from overloads and single-phasing when sized properly • Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short-circuit and overload protection • 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. * Indicating versions not Vdc rated.
