FAQs
Installation requires mounting on a sturdy wall with sufficient clearance for 34.27 in height and 31.5 in width. Ensure room for 9.35 in depth, connect to 480 V primary via the M48GD1H wiring terminals, and provision secondary 208Y/120 V out to the load bus. Verify the enclosure is rated NEMA 3R and observe the 115 °C rise rating for safe cooling. Follow local codes and refer to the Eaton datasheet for torque specs and terminal clearances.
The unit is a 15 kVA three-phase transformer with a 60 Hz frequency, 480 V primary, and 208Y/120 V secondary. It uses copper windings, has a 180 °C insulation rating, and supports a tap size of 2 at -5% FCBN. The enclosure is NEMA 3R, and it aligns with CSA, IEEE, ANSI, and UL certifications for safety and compliance.
Yes. It comes in a NEMA 3R enclosure designed for outdoor service and harsh environments. The unit does not require additional weather shielding, and its 115 °C rise rating helps manage heat under load. Always ensure adequate ventilation around the enclosure and follow installation guidelines to maintain enclosure integrity and regulatory compliance.
The P48G28T1518CSCUB is CSA Certified, IEEE Certified, ANSI, and UL Listed. These certifications verify safety, performance, and regulatory compliance across North American markets, reducing risk for procurement, enabling smoother audits, and supporting reliability in critical power-distribution applications.
You can expect lower lifecycle costs due to durable copper windings, robust insulation, and a compact footprint that reduces space and labor during installation. The wall-mount design speeds commissioning, while the reliable NEMA 3R enclosure minimizes weather-related maintenance. Together, these factors contribute to improved uptime and a shorter payback period for panel upgrades.
