FAQs
The unit offers floor-or-wall mounting and a NEMA 2 enclosure, making it suitable for indoor, dust-morsure protected environments. Plan for adequate space around the transformer for service access, ensure compliance with clearance requirements, and verify ambient temperature does not exceed insulation rating. Use proper conduit routing and allow for vibration isolation to maintain low noise performance.
Primary voltage is 480 V, secondary is 208Y/120 V, and the transformer is rated at 75 kVA (75 kVA apparent power). It operates at 60 Hz and is designed for three-phase distribution, providing stable voltage for industrial controls and machinery fed from 480 V sources.
Yes. The N48M28B7516CUSRLS50 complies with DOE 2016 Efficient requirements for dry-type distribution transformers and is UL Listed, indicating adherence to recognized safety and performance standards. This combination supports regulatory compliance, energy savings, and reliable operation in demanding industrial settings.
Best suited for indoor industrial spaces requiring robust protection (NEMA 2), quiet operation (50 dB), and reliable power for motor drives, machine centers, and control panels. Its copper windings and 220 °C insulation support higher thermal tolerance, while the floor-or-wall mounting provides installation flexibility in retrofit projects.
The 75 kVA, 480 V to 208Y/120 V design delivers stable power with reduced losses under DOE 2016 efficiency guidelines, contributing to energy-cost savings over time. Copper windings and a durable NEMA 2 enclosure lower maintenance needs, and UL listing simplifies procurement and compliance management, supporting faster project approvals and uptime improvements.
