FAQs
Plan for a sturdy mounting base compatible with frame 916A and a minimum clearance for ventilation. The unit weighs about 1281 lb, so use proper lifting equipment during installation. Consider the WS19 weather shield option for outdoor or harsh environments and ensure compliance with NEMA TP-1 and UL Listed requirements to simplify audits.
This transformer has a 480 V primary and a 208Y/120 V secondary, delivering 112.5 kVA at 60 Hz. It is designed for three-phase distribution, making it suitable for medium-load applications in manufacturing lines, distribution panels, and control cabinets where stable voltage is critical.
The unit provides taps at +2.5% and -2.5% (2 +2.5% and 4 -2.5%), allowing field adjustments to maintain voltage within tight tolerances as load and input voltage swing. This reduces equipment stress, improves performance of sensitive devices, and minimizes unnecessary breaker trips in variable-load environments.
The N48M28T12CUEELS47 is UL Listed and NEMA TP-1 compliant, meeting essential safety and efficiency standards. It also boasts a low sound profile of 47 dB, which is advantageous for installation in open-plan facilities, data centers, and noisy plant floors where sound reduction matters.
This three-phase, 112.5 kVA transformer is well-suited for motor control centers, power distribution panels, and equipment racks in manufacturing and process industries. Its copper windings, robust frame, and harmonic-friendly K-Factor design support reliable operation in environments with non-linear loads, enabling improved uptime and energy efficiency.
