Bussmann LPS-RK-200SP Low-Peak Class RK1 Fuse

The Bussmann LPS-RK-200SP is a 200 amp Low-Peak Class RK1 fuse designed for current-limiting protection in industrial power systems. This dual-element, time-delay fuse uses a cartridge body with blade-end connections (blade end x blade end) and is non-indicating. It is rated for up to 600 VAC and 300 VDC, with interrupting ratings of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC. The LPS-RK family meets UL 248-12 Class RK1 requirements and is part of Eaton's Bussmann series, commonly used to protect motors, drives, switchgear, and other high-current equipment in commercial and industrial applications. In its standard form, the LPS-RK-200SP provides current-limiting protection with a time-delay characteristic suitable for transient inrush, while offering a robust 200 A rating at these voltages. The line also includes tin-plated variants (for example LPS-RK-200SP-TP) and other RK1 ratings across the LPS family for different installation needs.
