Eaton LPS-RK-150SPI Fuse - RK1 Class, 150 A, 600 Vac
Part Number: LPS-RK-150SPI
Quick Summary
LPS-RK-150SPI fuse protects industrial power circuits with time-delay, current-limiting RK1 protection. Engineers often battle nuisance trips during startup surges; this device reduces misoperation while preserving fast fault clearing. It carries CE marking and RoHS alignment, and it embodies RK1 class fuse standards for reliable, plug-and-play integration. With documented specifications and standard footprints, it supports traceability, service planning, and scalable protection across panels. In production settings, the 150 A rating and 600 Vac operation enable safe, efficient protection of motors, heaters, and distribution circuits. Electrically isolated end caps and blade-end connections simplify installation, reduce wiring errors, and improve serviceability in retrofit and new builds.

Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, 70-600 A data sheet no. 1002
Feature → Time-delay, dual-element, current-limiting design provides selective protection during startup surges while still delivering short-circuit clearing. Business Impact → Reduces nuisance trips and downtime, improving overall equipment uptime and line efficiency in busy industrial environments. Application → Suitable for motor drives, conveyor systems, and power distribution panels where startup surges are common. Feature → Class RK1 fuse with blade end x blade end connection ensures compatibility with standard Bussmann RK1 holders. Business Impact → Simplifies replacement, reduces commissioning time, and minimizes modification needs during retrofits. Application → Ideal for retrofit projects and new builds using common RK1 mounting schemes. Feature → Electrically isolated end cap option enhances safety during maintenance and inspection. Business Impact → Lowers risk of accidental energization and simplifies service procedures. Application → Useful in high-vibration or enclosed environments where end-cap integrity matters. Feature → 150 A amperage rating and 600 Vac operating range deliver robust protection for a wide range of motors and heaters. Business Impact → Improves protection margins and system reliability, supporting compliant power distribution. Application → Widely applicable across industrial heating, motor control centers, and general-purpose protection stages. Feature → 300 kAIC interrupting capability at 600 Vac and 100 kAIC at 300 Vdc provides strong fault current handling. Business Impact → Enhances system safety and reduces downstream damage during fault events. Application → Critical in high-energy installations and dense power networks where fault currents are substantial.

FAQs
The LPS-RK-150SPI uses blade-end x blade-end connections that align with standard Bussmann RK1 fuse holders, enabling straightforward, drop-in replacement in compatible panels.
It is rated for 150 A with a 600 Vac maximum voltage, and offers an interrupt rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, supporting high-energy fault protection.
Yes. Its time-delay, dual-element, current-limiting design is well suited for motor drives, heaters, and general power distribution where startup surges occur but fast fault clearing remains essential.
Variants of the LPS-RK-150SPI can include an indicator option; confirm the exact product configuration (With Indicator vs Non-indicating) in the catalog or datasheet to match your maintenance and monitoring needs.
The fuse carries CE marking and RoHS compliance for European and global deployments, with a standard RK1 footprint and electrically isolated end caps that simplify installation, maintenance, and serviceability in retrofit or new-build projects.
