FAQs
The LPS-RK-7SPI is well suited for motor control centers, drives, and power distribution panels where brief inrush currents are common but precise fault clearing is necessary. With a 7 A rating and 600 Vac capability, it protects equipment during startup sequences while limiting damage from short circuits, supporting reliable, continuous operation in automation lines.
Select the correct RK1 class fuse with a 7 A rating and compatible voltage, then place it in the proper RK1 fuse holder. If you need status feedback, choose the indicator variant. Use the electrically isolated end caps for safer multi-end assemblies, ensure proper torque on connections, and verify clearances to prevent arcing during replacement.
Yes. The LPS-RK-7SPI is CE marked and RoHS compliant, aligning with European safety and environmental standards. This simplifies compliance documentation and approvals for European installations, reducing procurement friction in regulated markets.
The fuse provides a 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc, with voltage ratings of 600 Vac and 300 Vdc. This combination supports robust protection for high-current fault conditions while remaining suitable for both AC and DC sections in mixed-voltage panels.
Yes, variants exist with an indicator or non-indicating end caps. The indicator version offers immediate visual status, aiding maintenance and fault diagnosis. Its compact 5 in length and standard packaging simplify replacement, stocking, and field servicing in control panels and OEM assemblies.
