FAQs
For installation, ensure proper panel integration with three-phase 480 V input and correct 208Y/120 V secondary connections. Maintain adequate clearance for ventilation, follow the EE/OS enclosure requirements, and verify taps at +2.5% and -2.5% to fine-tune voltage regulation. Use appropriate surge protection and mechanical mounting suitable for the panel layout to maximize uptime.
Yes. This transformer is specified for a 480 V primary and a 208Y/120 V secondary, making it well-suited for control circuits and automation panels that require stable, low-voltage control power derived from a 480 V feed, with voltage regulation capable taps to reduce downstream fluctuations.
Key specs include the 225 kVA VA rating, 480 V primary, 208Y/120 V secondary, and the ±2.5% taps. The copper windings support high current with good conductivity, and the 80°C rise rating informs cooling and enclosure sizing. These factors influence transformer sizing, heat dissipation, and protection strategy in switchgear assemblies.
