Eaton Bussmann FRS-R-25 Fusetron 25A 600V AC Class RK5 Dual-Element Time-Delay Fuse

Description

Product Overview
The Eaton Bussmann FRS-R-25 is part of the Fusetron Class RK5 fuse series. It combines dual-element construction with time-delay and current-limiting characteristics for applications requiring coordinated overload and short-circuit protection.
The time-delay feature allows the fuse to tolerate certain temporary current surges without unnecessary operation. Correct fuse selection remains essential to protect motors, wiring and connected equipment according to the circuit design and manufacturer’s requirements.
