Selling Policy 25-000 - Distribution and Control Products and Services
Copper windings and a dry-type construction deliver durable, low-maintenance performance, minimizing oil-related risks and simplifying installation in restricted spaces. Business impact: improved reliability under non-linear loading translates to fewer outages and lower long-term maintenance costs. Application: ideal for modern manufacturing floors and PV integration where predictable power quality is essential. Tap settings—2 taps at +2.5% and 4 taps at -2.5%—provide precise voltage regulation, reducing flicker and protecting sensitive equipment. Business impact: tighter voltage control lowers equipment stress and extends component life. Application: critical loads near voltage limits, such as inverters and CNC drives. This unit’s 115 °C rise rating, UL Listed status, and NEMA TP-1 efficiency support regulatory compliance while limiting cooling requirements. Business impact: energy efficiency and safer operation reduce total cost of ownership. Application: facilities demanding reliable power with stringent safety standards. Electrostatic shielding plus the WS19 weather shield enable outdoor or harsh-environment deployments with fewer insulation concerns. Business impact: lower environmental protection costs and longer service intervals. Application: outdoor substations or exposed mechanical rooms. The 75 kVA rating, 480 V primary, 380Y/220 V secondary, copper windings, and 916AW frame combine to fit moderate-load distributions in compact footprints. Business impact: easier integration with existing switchgear and a smoother installation process. Application: data centers, mixed-use facilities, and PV-backed distributions seeking robust harmonic mitigation.

FAQs
This three-phase dry-type transformer weighs 436 lb and fits within a footprint of roughly 23.42 in by 28.22 in by 46.58 in. Plan for space for mounting on a stable base, allow ventilation, and install with the WS19 weather shield if outdoors. Connect 480 V primary and 380Y/220 V secondary, and use the ± taps to regulate voltage as needed.
The unit employs copper windings with electrostatic shielding and a dedicated harmonic mitigation design to limit harmonic currents. It maintains a zero phase shift and includes voltage-tap adjustments to keep system voltage within tolerance, reducing heat in downstream equipment and improving overall power quality for non-linear loads such as PV inverters.
Yes. With 75 kVA capacity, 480 V primary and 380Y/220 V secondary, it supports PV inverters and other non-linear, three-phase loads. The copper windings and 115 °C rise rating help manage thermal stress, while UL Listed certification and NEMA TP-1 efficiency support reliable operation in critical facilities.
The transformer is UL Listed and designed to meet NEMA TP-1 efficiency guidelines. Its housing is rated for a 115 °C rise, and it offers electrostatic shielding and the WS19 weather shield for protected operation in challenging environments, supporting compliance and long-term reliability.
With stainless-shielded construction, copper windings, and a robust 75 kVA rating, maintenance needs are reduced due to solid-state insulation robustness and a low oil-free design. The UL/NEMA-compliant configuration supports lower downtime and longer service intervals, contributing to favorable total cost of ownership in facilities adopting harmonic mitigation strategies.
