30A Fusetron FRS-R Cartridge Time Delay Cartridge Fuse, 4PK

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 Underwriter's Laboratories listed, CSA Canadian Standards Association certified.
