FAQs
Installation should begin with verifying the enclosure mounting location per the NEMA 1/NEMA 3R rating, then wiring to a three-phase 600 V bus with proper clearances. The unit uses a frame A1 and includes three midget-type fuses rated for 100,000 AIC. Ensure proper fuse protection, confirm phase sequence, and follow Eaton install guidelines to achieve rated 5 kVAR and maintain safety clearances.
Key specs include three-phase operation, 600 V voltage rating, 5 kVAR capacity, 4.90 A amperage, and an A1 frame. It uses three midget-type fuses with 100,000 AIC, and provides neon blown-fuse indicators with a protective guard. Enclosure options are NEMA 1 and NEMA 3R, with a 14-gauge steel shell finished in durable powder coating.
Yes, but the 240 V kVAR rating must be adjusted for 208 V operation by multiplying by 0.75. This ensures accurate kvar budgeting in lower-voltage configurations and helps avoid over- or under-sizing during project planning.
The 563PMURF is CSA Certified and UL Listed, providing essential safety and regulatory compliance for industrial installations. Enclosure protections include NEMA 1 and NEMA 3R, with a 14-gauge steel body and powder-coated finish to withstand varied indoor and outdoor environments.
Maintenance centers on visual and electrical checks of fuses and indicators; neon light status can signal fuse conditions quickly. The unit’s rated protection (three fuses, three indicators) reduces the risk of cascading faults. Expect energy savings from improved power factor and potential downtime reduction due to reliable, clearly indicated fault conditions, backed by a one-year warranty or 18 months from shipment.
