FAQs
Yes. This unit is designed for indoor installation with a NEMA 2 enclosure and a 916A frame. It uses a 200X wiring connection, supports 480 V primary and 208Y/120 V secondary, and operates at 60 Hz. Plan for standard clearances, ventilation, and access for routine maintenance and tap adjustments.
The transformer is three-phase, 75 kVA, with a 0° phase shift, and 480 V primary to 208Y/120 V secondary. It features tap changes of 2 at +2.5% and 4 at -2.5% to manage voltage swings. Copper windings offer high conductivity and durability, while the 115 °C rise rating indicates robust thermal performance under load.
Yes. The unit’s harmonic mitigation reduces THD and improves power quality for sensitive equipment. Its copper windings, sturdy enclosure, and precise voltage tapping support critical loads like servers, drives, and PLCs. The 75 kVA rating provides ample headroom for incremental load growth common in data centers and manufacturing lines.
Key certifications include UL Listed safety certification, and a NEMA 2 enclosure rating for indoor protection. Catalog notes reference compliance with NEMA ST-20 sound level standards, and electrostatic shielding is included as a protective feature. The combination supports reliable performance within regulated industrial environments.
The warranty runs for one year from installation or eighteen months from shipment, whichever occurs first. Maintenance requirements are typical for dry-type transformers: periodic inspection of connections, verification of taps, and routine thermal monitoring help ensure long-term reliability and minimize unplanned downtime.
