FAQs
This transformer is a dry-type distribution device rated for three-phase 60 Hz operation with a 480 V primary and 208Y/120 V secondary. It uses a 200X wiring connection and a footprint aligned with typical switchgear room layouts. For best results, mount in a ventilated indoor space, confirm clearance for the 48.56 in height and 28.22 in width, and connect per the 480 V to 208Y/120 V schematic. The tap options enable on-site voltage fine-tuning without additional equipment, simplifying commissioning.
The unit delivers 75 kVA with a 480 V primary and a 208Y/120 V secondary. It is a three-phase, 60 Hz transformer with phase shift of 0 degrees. Tap changes include two taps at +2.5% and four taps at -2.5%, allowing precise voltage adjustments under load. Copper windings and a dry-type construction support durable performance in demanding environments.
Yes. The transformer is specifically designed as a harmonic mitigating transformer suitable for PV-influenced and heavy industrial power systems. With NEMA TP-1 efficiency, UL Listing, and an 80 kA per phase secondary SPD note, it helps reduce harmonic distortion and surge risks while maintaining regulatory compliance and power quality in critical loads.
This unit is NEMA TP-1 compliant and UL Listed, with catalog notes indicating NEMA TP-1 efficiency. These certifications verify safety, performance, and efficiency for industrial installations. The product also features electrostatic shielding and weather protection (WS19), supporting reliability in varied environments while maintaining compliance with industry standards.
Maintenance is typical for dry-type transformers, focusing on insulation checks, thermal monitoring, and periodic electrical tests. The copper windings and robust frame reduce winding wear, while harmonic mitigation reduces neutral current and equipment stress, translating to lower energy losses and extended motor life. The result is lower maintenance costs, fewer replacements, and a faster return on investment in facilities with significant harmonic activity.
