FAQs
Installation requires aligning the bolted blade end connections with the mating terminations, tightening to the manufacturer’s torque specification, and ensuring clean, undamaged contacts. Verify the device is rated for the circuit voltage and current, and insert only into appropriately rated holders. Use protective PPE and follow lockout/tagout procedures during installation for safe commissioning.
The KRP-C-900SP combines a Class L construction with time-delay characteristics to tolerate temporary inrush currents while protecting against sustained faults. This yields selective tripping, reduces nuisance interruptions on motor starts, and provides faster fault clearance for feeders and drives—crucial for maintaining continuous production and protecting downstream equipment.
Yes. The fuse is rated for 600 Vac and 300 Vdc, making it appropriate for mixed-voltage industrial systems. Its high interrupt ratings (300 kA at 600 Vac and 100 kA at 300 Vdc) support safe isolation of faults in heavy machinery, conveyors, and process equipment while maintaining protective coordination with upstream devices.
Absolutely. The KRP-C-900SP is RoHS compliant and CE marked, ensuring it adheres to European safety and environmental standards. This is particularly valuable for global OEMs and facilities seeking compliant components for cross-border assemblies, reducing compliance risk during audits and product approvals.
The fuse contributes to a favorable ROI through reduced downtime from fewer nuisance trips, improved protection coordination, and a smaller panel footprint that lowers space and cooling costs. Its reliability for high current and robust interrupt ratings translate to longer asset life and lower maintenance intervals in critical feeder applications.
