Time-delay Provides motor overload, ground fault and short-circuit 10 seconds (minimum) at 500% of rated current. protection. When used in circuits subject to surge currents Catalog Symbol: FRS-R-(amp) such as those caused by motors, transformers and other Ratings: inductive components, these fuses can be sized close to full-load amps to give maximum overcurrent protection. Volts 600Vac, 300Vdc The time-delay feature makes it possible to use fuse amp Amps 65-600A ratings which are much smaller than those of non-time delay fuses. Considerable cost saving occurs by permitting the IR 200kA Vac RMS Sym. use of smaller size switches, panels and fuses themselves. 20kA Vdc Provides a good degree of short-circuit protection (greater Agency Information: current-limitation) to help protect downstream components from high fault currents. CE, UL Listed, Std. 248-12, Class RK5, Guide JDDZ, Gives motor running back-up protection to motors without File E4273 extra cost. CSA Certified, C22.2 No. 248.12, Class 1422-02, File 53787 Helps protect motors against burnout from overloads and single-phasing when sized properly.
