FUSETRON Energy Efficient FRS-R 1 Dual-Element, Time-Delay Fuses 10-60A Class RK5 600 Volt General Information: Dimensions - in Provides motor overload, ground fault and short-circuit 5 ( 0.031) protection. When used in circuits subject to surge currents .81 ( 0.008) such as those caused by motors, transformers and other /A to 30A inductive components, these fuses can be sized close to full-load amps to give maximum overcurrent protection. 5.5 ( 0.31) Permits the use of smaller and less costly switches. The 1.06 ( 0.008) time-delay feature makes it possible to use fuse amp ratings 35A to 60A which are much smaller than those of non-time-delay fuses. Considerable cost saving occurs by permitting the use of smaller size switches, panels and fuses themselves. Provides a higher degree of short-circuit protection (greater current-limitation) in circuits in which surge currents or temporary overloads occur. Catalog Symbol: FRS-R Helps protect motors against burnout from overloads. Current-limiting Gives motor running back-up protection to motors without Dual-element, time-delay 10 second (minimum) at 500% extra costs. rated current Helps protect motors against burnout from single phasing on Ratings: three phase systems. Volts 600Vac (or less) Simplifies and improves blackout prevention (selective 1 Amps 10-30A coordination). IR 200kA RMS Sym. Dual-element fuses can be applied in circuits subject to 20kA 300Vdc temporary motor overloads and surge currents to provide Amps 35-60A both high-performance, short-circuit and overload protection. IR 200kA RMS Sym. The overload element provides protection against low level 20kA 250Vdc overcurrent of overloads and will hold an overload which is Agency Information: five times greater than the amp rating of the fuse for a CE, UL Listed, Std. 248-12, Class RK5, Guide JDDZ, File E4273 minimum of ten seconds.
