Bussmann LPS-RK-175SP Fuse

The Bussmann LPS-RK-175SP is a high-current, low-peak Class RK1 time-delay cartridge fuse rated for 175 A with a 600 VAC and 300 VDC voltage rating, designed for bolt-mount installation in electrical panels and power-distribution gear. As part of Eaton’s Bussmann LPS‑RK Low Peak series, this non-indicating fuse uses a dual-element design to withstand brief overloads while protecting circuits from faults, and it carries an interrupting rating of up to 300 kA at 600 VAC and 100 kA at 300 VDC. For applications requiring fault indication, the LPS-RK-175SPI variant offers open-fuse indication, while the base LPS-RK-175SP remains non-indicating. This fuse is a cartridge type with bolt-mount termination, conforming to UL 248-12 requirements for Class RK1 devices. It is cataloged under the Bussmann lineup as part of Eaton’s electrical protection products and represents a standard RK1 protection option for high-current circuits operating at up to 600 VAC.
