FAQs
The N43M28T15X is a 15 kVA, three-phase transformer with a 416 V primary and 208Y/120 V secondary. It operates at 50–60 Hz, features K-13 design, and includes taps at +2.5% FCAN and -2.5% FCBN. Frame is 912B, windings are aluminum, and it includes an electrostatic shield and WS38 weather shield for enhanced protection and cooling.
The K-Factor nonlinear design helps mitigate harmonic currents generated by modern equipment, improving power quality and reducing thermal stress on transformers and upstream equipment. This leads to more stable voltage regulation, fewer maintenance events, and better efficiency across variable loads common in manufacturing lines and data-center-adjacent infrastructure.
The transformer occupies a footprint compatible with standard 912B frame installations and measures 16.5 inches in depth, 30 inches in height, and 23 inches in width. It weighs approximately 262 pounds, offering a balance of solid protection and manageable service access for installations in switchgear and panel rooms.
The N43M28T15X carries UL Listed certification, indicating compliance with recognized electrical safety standards. The warranty is Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first, providing assurance for field reliability and ongoing maintenance planning.
Plan for adequate ventilation to exploit the ventilated design, maintain clearances around the WS38 weather shield, and ensure access to taps (+2.5% and -2.5%). With aluminum windings and a 150 °C rise rating, position the unit where ambient temperatures and insulation requirements are within spec. Mounting should align with frame 912B norms for straightforward installation and serviceability.
