FAQs
Start by confirming the system voltage (480 V three-phase) and enclosure space for the C1 frame. Verify the existing control wiring and fuse protection match the three slottedblade fuses with 200 kAIC. Check that the enclosure supports indoor or outdoor placement (NEMA 1 or NEMA 3R). Finally, ensure mounting clearance and alignment with existing switchgear for a smooth retrofit.
The 7043PMURF delivers 84 A at 480 V with a 70 kVAR rating, enabling substantial reactive power support to raise the power factor. This reduces reactive current in the system, lowers utility penalties, and improves voltage stability under loaded conditions. For 208 V systems, apply the catalog note by multiplying the 240 V kVAR rating by 0.75 to approximate the equivalent 208 V performance.
The unit features a powder-coated 14 gauge steel enclosure with NEMA 1 and NEMA 3R ratings, making it suitable for indoor use and protected outdoor environments. Neon blown-fuse indicators are covered by a transparent weatherproof guard, aiding quick fault identification while preserving enclosure integrity in less-controlled settings.
The capacitor bank is UL Listed and CSA Certified, signaling conformance with recognized safety and performance standards. This helps satisfy regulatory requirements for electrical equipment in many facilities, supports insurance and procurement criteria, and provides assurance for long-term reliability in mission-critical applications.
Maintenance relies on standard LV practices: monitor the fuse indicators, inspect the enclosure for corrosion, and verify wiring integrity. The 1-year warranty (18 months from shipment) offers protection against manufacturing defects. ROI is driven by improved power factor, reduced energy penalties, and lower maintenance downtime due to clear fault indications and robust enclosure design.
