Description
The Eaton Bussmann FRN-R-2-1/2 is a dual-element, time-delay fuse designed to provide overcurrent protection in compatible industrial and electrical distribution systems. Its time-delay characteristic allows suitable temporary inrush currents, such as motor-starting surges, while providing protection against sustained overcurrent conditions.
The fuse belongs to the Fusetron Class RK5 range and features a current-limiting design for appropriately rated circuits.
