FAQs
Install in accordance with Class 1 Division 2 guidelines and use the NEMA 3R enclosure as specified. Ensure proper grounding and clearance around the transformer, and connect the 70A wiring with the correct secondary wiring. Set the -5% taps as required for voltage regulation under load, and follow the manufacturer notes for labeling and wiring to maintain compliance.
Key specs include three phase operation, 3 kVA rating, 480 V primary, 208Y/120 V secondary, 50/60 Hz, aluminum windings, and two -5% taps. This combination delivers stable voltage transformation for control panels and PLCs, minimizes voltage drop along feeders, reduces start-up trips, and supports reliable operation of sensitive equipment in varying line conditions.
Yes. The transformer uses a NEMA 3R enclosure with indoor-outdoor weathershield and is designed for hazardous locations. This enables safe outdoor mounting or placement near equipment, provided adherence to installation guidelines for hazardous environments and proper sealing against moisture and dust exposure.
The unit is UL Listed and rated for Class 1 Division 2 Groups C and D. These certifications indicate compliance with safety standards for hazardous locations, enabling procurement in regulated industries and simplifying site commissioning. The NEMA 3R enclosure further supports weather resistance and regulatory alignment for mixed indoor-outdoor installations.
The aluminum windings resist corrosion, contributing to longer service life with reduced maintenance. The -5% taps help maintain voltage under load, lowering test and recalibration needs. The rugged enclosure and compact frame reduce space and cabinet costs, delivering lower total cost of ownership and improved uptime in demanding industrial environments.
