Overview
The Cooper Bussmann FRS-R-110 is a Class RK5 time-delay, dual-element fuse engineered for high-performance circuit protection in industrial and commercial applications. Rated at 110 amperes with a 600 VAC/300 VDC voltage range, this current-limiting fuse combines the reliability of the Fusetron brand with superior overload and short-circuit protection. The dual-element design provides excellent coordination with protective devices while maintaining fast-acting current limitation for equipment safety.
