Product Description
The Bussmann Fusetron FRN-R-45 is a 45-amp, dual-element, time-delay Class RK5 fuse engineered for dependable overcurrent protection in industrial and commercial electrical systems. Its time-delay design tolerates temporary inrush currents, such as motor starts and transformer energizing, while providing fast interruption of sustained overloads and short circuits. With robust current-limiting performance and a high interrupt rating, the FRN-R-45 is ideal for use in panelboards, feeders, disconnects, and motor control centers.
