Cooper Bussmann FRS-R-125 Fusetron Time Delay Fuse is a time-delay (slow-blow) fuse designed to protect electrical circuits from overcurrent while tolerating short-duration surges. The FRS-R-125 model specifies a 125 amp current rating. As part of the Fusetron family from Cooper Bussmann, this fuse is intended for branch-circuit protection in electrical panels and equipment where brief inrush currents are common.
