The Bussmann FRN-R-110 Fusetron is a dual-element, time-delay cartridge fuse (Class RK5) rated at 110 A for 250 VAC and 125 VDC circuits. It is non-indicating and current-limiting, engineered to tolerate brief overloads before interrupting on a sustained fault. Its interrupting ratings are 200 kA at 250 VAC and 20 kA at 125 VDC. As part of the FRN-R family, this energy-efficient fuse is designed for reliable protection in electrical panels and equipment requiring fast response to overloads while accommodating short-duration surges.
