Cooper Bussmann FRS-R-150 Dual Element Time Delay Fuse

Cooper Bussmann FRS-R-150 dual-element time-delay fuse is a 150-amp overcurrent protection device in the Bussmann FRS-R family. The dual-element design provides time-delay operation, allowing short current surges to pass without immediate tripping and helping protect circuits during transient conditions. Model FRS-R-150 identifies the specific rating and configuration used in electrical installations requiring robust high-current protection. This time-delay fuse is intended for applications where brief overloads or startup surges may occur, safeguarding wiring and connected equipment without unnecessary interruptions. Backed by the Cooper Bussmann brand, the FRS-R-150 integrates with standard electrical protection schemes used in commercial and industrial systems that rely on reliable, high-current fusing.
