FAQs
Install with adequate ventilation and clearance around the unit, ensuring secure mounting that matches the 176 frame dimensions. Use the 519Y wiring connection and avoid taps to minimize points of failure. Confirm input is 208 V and output is 220 V for downstream equipment, and protect with appropriate fusing and panel labeling to maintain compliance.
The transformer provides a 208 V primary and a 220 V secondary at a 60 Hz frequency, with a VA rating of 3 kVA. This combination supports typical control circuits and light distribution loads in industrial settings, allowing reliable voltage conversion without excessive transformer sizing or impedance concerns.
Yes. The S29N25S03 uses a NEMA 3R enclosure and an indoor-outdoor weathershield rating, enabling indoor-outdoor installations. Its encapsulated aluminum-windings design minimizes exposure risks, while UL Listing provides safety assurance. For outdoor use, ensure proper mounting clearances and shielded pathways to maximize life in harsh environments.
The transformer is UL Listed, confirming compliance with recognized safety standards. The NEMA 3R enclosure supports weather resistance, aiding reliability in varied environments. These certifications help streamline procurement for regulated industries, support warranty terms, and reduce risk during audits and inspections while ensuring compatibility with standard industrial electrical practices.
Encapsulated construction reduces oil leakage risk and minimizes contamination, lowering maintenance needs. Aluminum windings offer good thermal performance with lighter weight, improving handling and installation efficiency. UL-listed transformers provide compliance confidence, potentially lower warranty disputes, and longer service life, delivering a favorable total cost of ownership over the equipment lifecycle.
