FAQs
Mount the LPS-RK-175SP-TP in standard RK1-compatible fuse blocks within panel boards. Ensure alignment with tin-plated contacts for corrosion resistance and proper torque on fuse links. Confirm voltage ratings of 600 V AC or 300 V DC per the circuit, and provide adequate clearance and ventilation for heat dissipation during fault conditions.
The fuse provides 175 A continuous rating with an interrupt rating of 100 kAIC at 300 Vdc and 300 kAIC at 600 Vac, and voltage ratings of 600 V AC / 300 V DC. These ratings enable safe protection for high-inrush loads in AC drives and DC bus circuits, while maintaining selective coordination with adjacent protection devices.
Yes. Its time-delay feature accommodates motor inrush, and the current-limiting design helps limit damage during faults. It is appropriate for motor control centers, drive panels, and other motor-protection scenarios where uptime and fault clearance are critical, provided the 175 A rating matches the motor current and system coordination requirements.
The LPS-RK-175SP-TP is RoHS compliant, aligning with environmental and process restrictions for hazardous substances. While CE/SIL/IP certifications are not listed in the provided data, RoHS compliance ensures responsible material usage; for broader regulatory coverage, verify with Eaton documentation and regional requirements.
The high interrupt capability and time-delay characteristics help reduce downtime by preventing nuisance trips during startup while protecting feeders from short circuits. Tin-plated contacts improve longevity in harsh environments, and the RK1-class compatibility streamlines procurement and stocking. Overall, users can expect improved equipment protection, easier maintenance planning, and lower total cost of ownership.
