Feature UNIPAK design provides compact footprint and straightforward installation, enabling faster retrofits in existing switchgear while preserving protective access. Business Impact This reduces project timelines and field labor costs, delivering measurable ROI in new builds or capacity upgrades. Application Use in three-phase 240V systems to achieve power-factor correction for motors, pumps, and HVAC loads. Feature 75 kVAR rating at 240V with 180A amperage delivers robust reactive power support, improving system voltage profile and reducing conductor current. Business Impact Lower utility penalties and energy waste by keeping the facility within desired power-factor ranges, with predictable performance across load swings. Application Ideal for low voltage fixed capacitor bank installations in industrial plants, data centers, and commercial facilities seeking reliable PF correction. Feature EN closure rated NEMA 1, NEMA 3R and 14 gauge steel with durable powder coat finish offers rugged protection in various environments. Business Impact Enhanced durability translates to reduced maintenance intervals and extended service life, supporting long-term TCO goals. Application Suited for installations requiring visible fault indication via red neon lights protected by a weatherproof guard, simplifying maintenance checks. Feature Three slotted-blade fuses with 200,000 AIC and three indicator lights deliver clear fault signaling and fast isolation. Business Impact Improves safety and reduces downtime by enabling quick fault detection and selective fuse replacement. Application Fits within standard frame size C2 and maintains compatibility with common LV switchgear. Feature Warranty and service terms provide peace of mind with a one-year installation-based or eighteen-month shipment-based coverage, supporting long-term asset reliability. Business Impact Reduces risk and unplanned downtime during commissioning and operation, preserving uptime and asset value. Application Suitable for ongoing reliability programs and audits in regulated facilities.

FAQs
The 7523PMURF requires a stable, indoor or outdoor-ready location with access to LV switchgear. Its NEMA 1,3R enclosure supports indoor use and weather-protected outdoor spaces. The unit fits a C2 frame and weighs about 100 lb, so plan for appropriate mounting hardware, clearance for fuses and indicator lights, and suitable lifting provisions during installation.
Yes, you can operate the bank on 208V systems, but the kVAR rating changes. Multiply the 240V kVAR rating by 0.75 to estimate the effective kVAR at 208V. For this unit, 75 kVAR at 240V translates to 56.25 kVAR at 208V, so PF correction will be proportionally lower on 208V service.
The bank includes three slotted-blade fuses with 200,000 AIC and three neon indicator lights. The indicators are guarded with a weatherproof cover to prevent damage, and the three-fuse three-light configuration enables quick fault recognition and safe isolation during maintenance.
The unit is UL Listed and CSA Certified, underscoring compliance with safety and performance standards for electrical equipment. These certifications support regulatory acceptance, safer operation, and easier commissioning in regulated facilities or data centers.
Eaton provides a one-year warranty from date of installation or eighteen months from shipment, whichever occurs first. Service typically covers replacement of defective components and on-site support for commissioning, with standard terms aligning to Eaton’s Selling Policy 25-000.
