FAQs
The N48M47T3016 is designed for 480 V three‑phase input and provides a 480Y/277 V secondary. With a 30 kVA rating and 60 Hz operation, it suits industrial power distribution. Aluminum windings and a NEMA 2 enclosure support indoor installation, while 283B wiring and tap options (+2.5%, −2.5%) enable voltage regulation across your load. Assess panel clearance, mounting, and cooling needs before installation.
This transformer is UL Listed and meets DOE 2016 Efficient standards, with catalog notes referencing 10 CFR Part 431 (2016) Efficient. These certifications confirm safety compliance, energy efficiency, and regulatory alignment for federal and commercial installations. Verify local codes and site requirements during procurement to ensure full regulatory conformance.
Plan for floor or wall mounting with upright orientation in a clean indoor environment. The unit weighs 427 lb and measures about 36.88 in high, 24.88 in wide, and 21.13 in deep, which affects room layout and clearance. Use the NEMA 2 enclosure in sterile or semi‑indoor spaces, account for cooling needs, and consider the electrostatic shield option for EMI control.
Best suited for industrial power distribution tasks such as providing 480V input to a 480Y/277V network for machines, drives, and control panels. The K‑Factor 13 nonlinear design helps with harmonic mitigation on demanding loads, while the 30 kVA rating supports moderate to heavy panel boards. Use in environments requiring robust protection, consistent voltage, and energy efficiency under varying loads.
Maintenance is typically minimal for ventilated, shielded transformers with solid insulation. DOE 2016 efficiency reduces operating losses, contributing to lower cooling costs and extended service life. Factor in upfront weight, enclosure protection, and potential weather shielding when calculating TCO, but expect reliable performance with routine visual inspections and periodic connection checks.
