About this product
Designed to protect electrical circuits from overloads and short circuits, this Class RK5 dual-element time-delay fuse (model HCNR020) supports temporary motor overloads and surge currents while maintaining strong short-circuit protection. Rated 20 A and 250 V AC with high interrupting capacity up to 200 kA (and 125 V-150 V DC up to 50 kA), it helps reduce nuisance blows in motor and feeder applications by holding an overload up to 5x the amp rating for at least 8 s. The 9/16 in x 2 in (14.3 mm x 50.8 mm) size supports standard installations in service entrance switches, switchboard mains and feeders, motor control centers, and motor branch circuits, and complies with UL248-12 specifications. Compatible with Bussmann BP/FRN-R-20, Edison ECNR20, Littelfuse FLNR020.T / FLN-R-20 / FLNR-20; includes 2 fuses per package.
