Time delay fuse

FUSETRON 250 V FRN-R and 600 V RFS-R energy-efficient, dual-element, time-delay fuses are manufactured by Cooper Bussmann and allow for closer sizing to load with smaller fuse amp ratings than non-time-delay fuses on most motor and transformer primary applications.

FUSETRON 250 V FRN-R and 600 V RFS-RFUSETRON 250 V FRN-R and 600 V RFS-R energy-efficient, dual-element, time-delay fuses are manufactured by Cooper Bussmann and allow for closer sizing to load with smaller fuse amp ratings than non-time-delay fuses on most motor and transformer primary applications. These fuses fit any class K5 or H fuse blocks and holders, and with a 2:1 selective coordination amp ration, they prevent overcurrent events from opening upstream fuses. Features include a 200 kA interrupting rating for protection against fault currents, and insulated end caps to reduce exposure to live parts and to extend air gap distance between blades of adjacent mounted fuses or to housing.
