The Bussmann series FRS-R-200 is an energy effcient, dual-element, time-delay Class RK5 fuse and is part of our FUSETRON line of fuses. Its dual-element design provides the best time-delay for better protection of equipment such as power panelboards, combination starters, motor control centers, machinery disconnects, and safety switches. Dual element fuses feature separate overload and short-circuit elements to provide the same short circuit protection as a fast acting fuse with the added benefit of letting inrush currents pass without opening the fuse. As a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse). This is necessary for equipment that regularly experiences short-term power surges, such as when a motor or transformer strarts up.
