Eaton 75MCSR2313W Capacitor Bank - NEMA 3R Weather-Resistant
Part Number: 75MCSR2313W
Quick Summary
Eaton LV AutoVAR 300 capacitor bank improves power factor and reactive power management in low-voltage, three-phase industrial systems. Maintaining poor power factors can drive higher energy costs, cause voltage instability, and shorten the life of motors and drives. This unit carries IEEE Std. 18, CSA C22.2 No. 190, UL 810, and UL 508A certifications, signaling robust electrical safety and regulatory compliance. With wall-mounted installation and weather-resistant NEMA 3R construction, it fits compact spaces while withstanding demanding environments. Designed for 240 V systems at up to 180 A and 75 kVAR, it delivers reliable, scalable power factor correction for manufacturing and processing facilities.

The 75 kVAR, 240 V, 180 A, three-phase configuration delivers targeted reactive power support to stabilize voltages and reduce utility penalties, translating into lower operating costs and improved motor efficiency in demanding manufacturing lines. Its wall-mounted design saves floor space and simplifies retrofits or new installations in restricted electrical rooms, enabling faster project execution. The weather-resistant NEMA 3R construction ensures reliable operation in outdoor or damp environments, lowering the risk of downtime due to weather exposure and reducing enclosure costs. Certifications including IEEE Std. 18, CSA Std. C22.2 No. 190, UL 810, and UL 508A provide confidence in safety, performance, and code compliance for facilities subject to rigorous audits. Comprehensive dimensions and a 250 lb footprint support accurate planning, installation, and logistics for plant-wide deployments. A one-year warranty from installation (or 18 months from shipment) plus five years on capacitor cells minimizes long-term maintenance risk and supports predictable ROI.

FAQs
The Eaton 75MCSR2313W is a wall-mounted low-voltage capacitor bank designed for 240V three-phase services. Plan for a 36 inch depth, 60 inch height, and 13.67 inch width footprint, with an approximate 250 lb weight. Ensure accessible service clearances, proper mounting, and adequate heat dissipation in a dry, code-compliant electrical room.
The unit provides 75 kVAR of reactive power at 240V with a continuous current rating of 180A at 60 Hz in a three-phase configuration. It supports power factor correction and voltage support for varying facility loads, helping reduce utility penalties and improve motor efficiency when integrated with existing 240V feeders.
Yes. The design features weather-resistant NEMA 3R construction suitable for outdoor or damp environments when mounted in a protected enclosure. Always confirm enclosure ratings, maintain proper clearances for heat dissipation, and follow Eaton installation guidelines to ensure safe, reliable operation.
Key certifications include IEEE Std. 18, CSA Std. C22.2 No. 190, UL 810, and UL 508A, validating electrical safety and performance for North American installations. Verify project requirements for these standards during specification and ensure supporting documentation is available for audits and commissioning.
Warranty covers one year from installation or 18 months from shipment, whichever occurs first, with an additional five-year warranty on capacitor cells. This reduces long-term maintenance risk and supports predictable ROI. Eaton also offers field support, parts, and replacements to sustain uptime and project value.
