Cooper Bussmann FRS-R-350 Industrial High Current Fuse

The Cooper Bussmann FRS-R-350 is an industrial high-current fuse rated for 350 amperes, described as a FuseTRON 350 Amp fuse with model FRS-R-350. Designed to protect electrical circuits in heavy-duty industrial power systems, this device interrupts current flow when overcurrent conditions occur, helping prevent damage to wiring, equipment, and downstream components. The FRS-R-350 designation identifies the exact rating and form factor within the FuseTRON family, making it a precise replacement or integration piece for high-current protection needs in panels, switchgear, feeders, and other industrial installations where robust current handling is essential. As a Cooper Bussmann product, it carries the brand's lineage of electrical protection devices, and its 350 A rating provides a clear specification for coordinating with upstream protective devices in your distribution scheme.
