Bussmann FRS-R-3-2/10 Fusetron Class RK5 Dual-Element Time-Delay Fuse, 600V

Bussmann FRS-R-3-2/10 Fusetron Class RK5 Dual-Element Time-Delay Fuse, 600V

The Bussmann FRS-R-3-2/10 is a Fusetron-series dual-element, time-delay fuse rated 3-2/10 amps at 600V, engineered to deliver reliable overcurrent protection for branch circuits and motor loads. As a Class RK5 fuse, the FRS-R-3-2/10 combines a fast-acting short-circuit element with a thermal time-delay overload element, allowing it to ride through temporary inrush and motor-starting currents without nuisance opening while still responding quickly to true fault conditions. Its current-limiting design helps reduce let-through energy during a fault, protecting downstream conductors and equipment. The FRS-R-3-2/10 fits standard Class H/RK5 fuse clips and fusible disconnect switches used throughout commercial and industrial electrical systems, and it is designed for applications where dependable, time-delay overcurrent protection is required across motor branch circuits and general power distribution equipment.
