Bussmann LPS-RK-70SP Low-Peak Dual Element Time Delay Class RK1 Fuse

The LPS-RK-70SP is Eaton Bussmann’s Low Peak RK1 fuse—a dual-element, time-delay, current-limiting device rated at 70 A with a voltage range up to 600 VAC and 300 VDC. This non-indicating fuse combines Low Peak geometry with Class RK1 performance to tolerate brief inrush currents while reliably interrupting sustained overloads. It carries a 300 kA interrupting rating at 600 VAC and 100 kA at 300 VDC, making it suitable for motor circuits, power distribution panels, and other industrial applications that require solid overcurrent protection without nuisance tripping. The LPS-RK-70SP adheres to UL Standard 248-12 for Class RK1 fuses, aligning with a broad ecosystem of RK1 holders and blocks. With its 70 A rating and compatibility across 600 VAC / 300 VDC, this fuse is a practical choice for medium-to-heavy load circuits where dependable short-circuit and overload protection is essential.
