Eaton LPS-RK-250SP Fuse - Class RK1, 600 Vac RoHS CE
Part Number: LPS-RK-250SP
Quick Summary
Eaton LPS-RK-250SP fuse provides reliable, time-delay protection for industrial power circuits and motor control panels. Engineers face nuisance trips from inrush currents and mis-sized protection, which can escalate downtime and maintenance costs; this dual-element fuse minimizes those events while still delivering fast fault interruption. The device carries RoHS compliance and CE marking, supporting global regulatory needs, and its Class RK1 rating with a 250 A amperage rating anchors protection for demanding applications. Designed for blade-end connections and electrically isolated end caps, it installs quickly in standard enclosures, easing stocking and field replacements. By combining robust protection with simple installation, it helps reduce spare-part inventories while improving overall line reliability.

Bussmann series Fuseology
Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, 70-600 A data sheet no. 1002
Time-delay, dual-element, current-limiting design delivers dependable protection against fault currents while tolerating motor inrush. This minimizes nuisance trips and reduces wear on motors and drives, translating to lower maintenance costs and extended equipment life in manufacturing, packaging, and process plants. The fuse’s high interrupt ratings, 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, enable safe disconnection of large fault faults without collateral damage in panel boards and MCCs. Class RK1 with blade-end connections provides quick, secure installation in standard enclosures, improving serviceability and stock management. Electrically isolated end caps enhance safety during installation and maintenance, while RoHS compliance and CE marking ensure regulatory alignment across global sites. The 11.63 in length and 2.36 in width/height deliver a compact, standard footprint compatible with conventional protection schemes, reducing retrofit time and spare-parts complexity. Non-indicating status requires panel- or system-level monitoring, simplifying indicator integration in busy control rooms.
