Eaton LPS-RK-8SPI Fuse - Class RK1 CE Marked, 600 Vac
Part Number: LPS-RK-8SPI
Quick Summary
Eaton LPS-RK-8SPI fuse provides reliable time-delay overcurrent protection for industrial control panels and motor circuits. This design addresses nuisance trips and poor selectivity that disrupt production and complicate maintenance. The device complies with CE Marking and belongs to Class RK1, offering time-delay, dual-element protection with a 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc. By aligning with the Bussmann RK1 family, it delivers predictable coordination, faster fault clearance, and safer panel operation. The product supports both indicating and non-indicating variants, and its electrically isolated end caps simplify installation in OEM controls while reducing field wiring risk.

FAQs
The LPS-RK-8SPI is designed for Bussmann RK1 form-factor installations in industrial panels and feeders. Its 5 in length and 0.81 in width fit standard RK1 slots, and its 8 A rating aligns with common motor and control circuit protection needs. It is compatible with both indicating and non-indicating end-cap configurations, simplifying retrofit in existing control panels.
Key ratings include 8 A amperage, 600 Vac voltage, and interrupt ratings up to 300 kAIC at 600 Vac (and 100 kAIC at 300 Vdc). It is a time-delay, dual-element current-limiting fuse, providing fast fault clearance while tolerating inrush events common in automation equipment.
LPS-RK-8SPI variants cover both indicating and non-indicating options. Indicating variants assist troubleshooting by signaling fault status, reducing service time, while non-indicating versions minimize visual indicators in cleanroom or space-constrained panels. Your choice impacts diagnostics and panel aesthetics without compromising protection.
The fuse is CE marked for regulatory compliance. It belongs to Class RK1 and is designed for reliable protection in industrial environments, supporting safe operation and coordinated protection across automated systems.
The LPS-RK-8SPI provides predictable fault isolation with high interrupt ratings, reducing downtime from random fuse blows. Time-delay behavior improves process continuity, while compatible RK1 form factors simplify stocking and replacements, lowering maintenance costs and safeguarding equipment life.
