FAQs
For proper installation, ensure clearance for access and cooling, mount within a NEMA 3R rated enclosure, and provide adequate support for the 918AN frame. Plan for the 277 A wiring connection and utilize the +2.5% / -2.5% taps to correct voltage during startup or line fluctuations. Outdoor or indoor locations must align with the indoor-outdoor Weathershield capability.
Key specs include a 150 kVA rating, 60 Hz frequency, three-phase operation, 480 V primary, 600 V secondary, aluminum windings, and a DT-3E design with a NEMA 3R enclosure. The transformer supports 277 A full-load current and provides 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN for voltage regulation.
Yes. The 480 V to 600 V secondary configuration, paired with DT-3E enclosure and UL Listed safety, makes it well-suited for panel boards, process controls, and machine tooling. The 150 kVA rating provides ample headroom for balanced three-phase loads, while the taps allow voltage fine-tuning under fluctuating supply conditions.
The unit carries UL Listed safety certification and uses a NEMA 3R enclosure, enabling both indoor and outdoor installations. This combination supports compliance with safety standards while providing weather-resistant operation in mixed environments and helping mitigates risks in harsh facilities.
The product ships with Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever comes first. Routine maintenance includes checking terminal connections, inspecting the enclosure for seals, and verifying cooling pathways remain unobstructed. The non-ventilated design reduces cooling-related maintenance compared with ventilated designs.
