Three-phase 480 V operation with a 75 kVA rating is engineered to restore power quality under varying industrial loads. This directly reduces line current, lowers transformer stress, and minimizes utility penalties, making it ideal for motors, drives, and lighting in manufacturing environments with steady demand. The fixed Harm Cap design provides reliable performance with no moving parts, translating to lower maintenance costs and longer service life, which decreases downtime and enhances plant availability. CSA Certified UL Listed certification ensures North American safety and compliance, streamlining procurement and installation for data centers, processing plants, and assembly lines. The compact footprint—12.1 in deep, 26.3 in high, 9.1 in wide, 55.2 lb—facilitates retrofit and enclosure compatibility, enabling faster integration in existing electrical rooms. With 75 kVA capacity, this bank delivers meaningful energy efficiency gains, reducing utility charges while maintaining voltage stability on critical feeders. Compatibility with Eaton LV Unipak systems and standard wiring practices supports quick upgrades; for variable harmonic profiles, consider combining fixed banks with supplementary solutions to achieve broader dynamic control.

FAQs
Ensure enclosure space matches the unit’s 12.1 in depth, 26.3 in height, and 9.1 in width; provide a suitable disconnect or switchgear integration point; verify correct phasing and wiring per NEC guidelines; use rated cabling and secure grounding; confirm compatibility with existing Eaton LV Unipak mounting patterns for a straightforward retrofit.
The 75 kVA rating supplies a substantial reactive power correction for three-phase loads, improving power factor and reducing line current. This lowers transformer heating, reduces electrical losses, and minimizes utility penalties. It is especially effective for motor drives and high-harmonic equipment commonly found in manufacturing and packaging facilities.
Yes. The fixed Harm Cap design provides reliable, maintenance-light harmonic mitigation and PF correction suitable for facilities with steady loads. It integrates with standard 480 V three-phase power distribution and aligns with CSA Certified UL Listed safety requirements, making procurement and commissioning straightforward for mission-critical environments.
The unit is CSA Certified and UL Listed, demonstrating adherence to recognized safety and performance standards. These certifications streamline vendor qualification, support regulatory compliance, and simplify documentation for audits, tenders, and facility owner-operator programs across North American sites.
Expect lower ongoing maintenance due to a fixed-capacitor design with no moving parts, translating to reduced service interruptions. Energy cost savings from improved PF and lower penalties contribute to a favorable payback period, while dependable operation minimizes downtime. Asset life is supported by standard safety certifications and compatibility with existing switchgear.
