Eaton 5043PMURN LV Unipak Capacitor Bank - UL Listed
Part Number: 5043PMURN
Quick Summary
Eaton LV Unipak capacitor bank provides reliable reactive power support for low-voltage industrial distribution. When power quality slips under variable loads, utilities may impose penalties and equipment can suffer voltage sags, driving up operating costs. This unit carries UL Listed and CSA Certified safety marks, ensuring compliance and traceable performance in critical installations. Engineered for three-phase 480 V systems with a 60 A rating and a 50 kVAR output, it helps facilities reduce reactive energy charges and stabilize voltage. The Unipak design uses a durable 14 gauge steel enclosure with powder coating and a B1 frame, delivering robust, maintenance-friendly operation in manufacturing floors and outdoor spaces when installed in NEMA 1 or NEMA 3R environments.

Selling Policy 25-000 - Distribution and Control Products and Services
UNIPAK fixed capacitor banks deliver compact, factory-wired units that simplify panel integration for low-voltage, three-phase systems. This reduces field wiring, shortens commissioning times, and lowers total installed cost while delivering a 50 kVAR rating at 480 V for reliable power-factor correction in manufacturing lines. Durability comes from a 14 gauge steel enclosure with durable powder coat and a B1 frame, enabling long service life in harsh plant environments with minimal maintenance. The enclosure options cover indoor and outdoor installations (NEMA 1 and NEMA 3R), improving safety and compliance in motor-control centers and feeder panels. Certifications from UL Listed and CSA Certified support regulatory compliance and third-party validation for audits and upgrades. Catalog notes guide voltage-based derating to ensure correct kVAR sizing when voltage conditions change, reducing the risk of under- or over-correction and supporting accurate harmonic management and energy efficiency goals.

FAQs
Install the Unipak unit in a suitable enclosure supporting NEMA 1 or NEMA 3R conditions. Mount on a B1 frame, connect three-phase leads to the panel bus, and ensure proper clearance for heat dissipation. Verify a 60 A rating and 50 kVAR output, then follow Eaton’s installation guidelines and applicable electrical codes for safe commissioning and labeling.
The product is rated at 50 kVAR for 480 V operation, with a 60 A amperage rating. Per Eaton catalog notes, multiply the 240 V kVAR rating by 0.75 to estimate the kVAR value at 208 V. For other voltages, use manufacturer derating tables and perform final verification during system design to ensure precise reactive power correction without overcompensation.
Yes. The unit supports outdoor placement when installed in the NEMA 3R-rated enclosure, which provides rain and ice protection suitable for exposed locations. For outdoor use, ensure appropriate mounting, ventilation, and enclosure integrity, plus compliance with local codes and environment-specific derating and protection measures.
The 5043PMURN is UL Listed and CSA Certified, confirming compliance with recognized safety and performance standards. These certifications help satisfy regulatory audits, procurement requirements, and customer safety policies, reducing risk for electrical installations in industrial facilities and enabling smoother maintenance and module replacement.
Warranty is Eaton’s Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This, combined with manufacturer support, parts availability, and documentation, lowers lifecycle risk, improves maintenance planning, and enhances return on investment by reducing unexpected repair costs and downtime.
