The Cooper Bussmann Fusetron BP/FRN-R-100 is a Class RK5 dual-element, time-delay, current-limiting cartridge fuse rated at 100 Amps and 250V. Its dual-element design provides reliable motor overload, ground fault, and short-circuit protection, helping prevent motor burnout from overloads and single-phasing on three-phase systems. Select ratings offer optional open fuse indication for added convenience.
These time-delay fuses are ideal for circuits subject to temporary motor inrush currents, simplifying selective coordination for blackout prevention. UL Listed and sold in a convenient carded 5-pack, they are a trusted solution for industrial motor branch circuit and feeder protection applications.
