Bussmann FRS-R-2 Fusetron 10 Amp Time Delay Fuse

Bussmann FRS-R-2/10 Fusetron dual‑element, time‑delay fuse in the RK5 class is rated for 600 VAC / 300 VDC with a 2/10 A rating, delivering 200 kA interrupting capability at 600 VAC and 20 kA at 300 VDC. This current‑limiting, time‑delay device is designed to tolerate brief overloads such as motor inrush while reliably interrupting sustained faults, making it well suited for branch circuits in industrial control panels, transformers, and power distribution. The cylindrical fiberglass body measures 0.81 in in diameter by 5 in long and uses ferrule terminals on both ends for a secure, easy connection, and it is produced in a non‑indicating configuration within the Bussmann lineup. With a minimum 10‑second response at 500% of rated current, the FRS‑R‑2/10 provides a predictable, slow‑actuation profile that helps prevent nuisance trips during startup or transient surges, while still delivering fast protection when a fault persists. This fuse is part of Eaton’s Bussmann FRS‑R family (Class RK5), offering reliable protection for low‑to‑medium voltage applications where dual‑element, time‑delay performance is required.
