Bussmann FRS-R-30ID Fuse

FRS-R-30ID is Eaton Bussmann’s Fusetron dual‑element, time‑delay fuse in Class RK5 form, rated at 30 A with a 600 V AC / 300 V DC voltage rating and current‑limiting capabilities. The “ID” suffix signifies open‑fuse indication, providing visible status when the fuse has operated, a feature supported by the family’s design. It offers an interrupting rating of 200 kA at 600 VAC and 20 kA at 300 VDC, aligning with its use in electrical and industrial applications requiring reliable overcurrent protection. As part of the FRS‑R series, this fuse combines dual‑element construction with RK5 packaging to fit standard Bussmann fuse holders, delivering protection for branch circuits and equipment in environments where standard Bussmann fuses are employed. This 30 A, 600 VAC/300 VDC rated Fusetron device is intended for use in systems that require precise time‑delay characteristics and a visible indication of fuse status without compromising protection criteria.
