Product Description
The Bussmann LPS-RK-175SP Fuse is a high-performance 175 amp, dual-element, time-delay fuse engineered to provide dependable overcurrent protection in industrial and commercial electrical systems. Part of the Low-Peak RK1 family, this fuse features current-limiting technology that reduces let-through energy during short circuits and helps protect downstream components. Its time-delay characteristic tolerates harmless temporary overloads — such as motor starts — while interrupting sustained overloads quickly. Rated for 600 V AC and 300 V DC with a high interrupting capacity, it’s ideal for feeder circuits, motor loads, and power distribution applications.
