20A Fusetron FRS-R Cartridge Time Delay Cartridge Fuse

Fusetron dual-element time-delay current limiting fuses. Provide motor overload ground fault and short-circuit protection. When used in circuits subject to surge currents such as those caused by motors transformers and other inductive components these fuses can be sized close to full-load amperes to give maximum overcurrent protection. The time delay feature makes it possible to use fuse ampere ratings which are much smaller than those of nontime delay fuses. Provide a higher degree of short-circuits in which surge currents or temporary overloads occur. Helps protect motors against burnout from overloads. 600V. UL (Underwriters Laboratories) listed CSA (Canadian Standards Association) certified.
