FAQs
Plan for a NEMA 2 enclosure with ample clearance for a 324 lb unit. Mount on a stable surface compatible with the 912D frame, wire the 208 V primary to the supply bus and connect the 480Y/277 V secondary to the distribution circuits. Use the two +2.5% taps and four -2.5% taps to fine-tune voltage. Verify 60 Hz operation and ensure proper cooling in semi-enclosed spaces.
Primary voltage is 208 V, secondary voltage is 480Y/277 V. Tap settings include 2 taps at +2.5% and 4 taps at -2.5% to accommodate line variations and maintain regulated output under load changes.
Yes. With a 30 kVA rating and 3-phase 60 Hz performance, it supports motor drives, PLC power, and control panels. The dual taps help maintain voltage accuracy, while the NEMA 2 enclosure protects the transformer in standard industrial environments.
The unit is UL Listed and CSA Certified, with a NEMA 2 enclosure and DT-3 construction. These certifications simplify regulatory approvals and supplier qualification for panel builders and integrators.
Warranty terms follow Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This provides assurance for installation timelines and long-term maintenance planning.
