FAQs
The N48M47B4516 uses a floor or wall mounting configuration with a sturdy NEMA 2 enclosure suitable for indoor use. Typical installation requires adequate clearance for cooling, service access, and wiring routing via 283B connections. Its 31.5 in depth, 34.5 in width, and 51 in height define a relatively compact footprint for a 45 kVA three‑phase unit, while the 632 lb weight necessitates appropriate handling equipment during deployment.
K-Factor 13 denotes a nonlinear transformer design optimized for harmonics, improving power quality under diverse load profiles. When paired with DOE 2016 Efficient criteria, the transformer delivers lower losses and better thermal performance at an 80 °C rise. This translates to more stable voltages, reduced cooling energy, and enhanced reliability for drives and other nonlinear loads on a 480 V distribution network.
Yes. The unit provides a 480Y/277 V secondary suitable for three-phase systems, enabling a centralized step-down from 480 V to a usable 277 V line-to-neutral for controls and lighting circuits. With a 45 kVA rating and 60 Hz operation, it supports typical plant feeders and control panels while maintaining voltage regulation under variable load.
Key certifications include UL Listed safety certification and DOE 2016 Efficient compliance, ensuring electrical safety and energy efficiency. The unit also adheres to 10 CFR Part 431 (2016) for efficient products, and the NEMA 2 enclosure supports indoor environmental protection. Confirm compatibility with your plant’s regulatory and safety requirements before installation.
Benefits include energy savings from DOE 2016 efficiency, reduced maintenance due to durable aluminum windings and rugged NEMA 2 enclosure, and improved system reliability from K-Factor 13 nonlinear design and electrostatic shielding. Weight and footprint considerations simplify site planning, while voltage taps provide runtime regulation to minimize equipment wear and downtime, contributing to a favorable return on investment.
