FAQs
The N43M28T49X is a three-phase transformer with a 416 V primary and a 208Y/120 V secondary, designed for installation in industrial environments. It uses aluminum windings, an electrostatic shield, and the WS34 weather shield for outdoor or harsh indoor applications. Plan for the 30.68 in depth, 62.18 in height, and 31.44 in width footprint, and ensure appropriate lifting and mounting provisions for its 1405 lb weight.
K-Factor nonlinear ventilation optimizes thermal management under non-sinusoidal loading, helping to minimize overheating and voltage drift during harmonic-rich operation. This translates to improved reliability for sensitive loads, better efficiency under dynamic loads, and reduced risk of insulation aging. It is particularly advantageous in facilities with variable-speed drives and programmable logic controllers.
Yes. With a 150 kVA rating, 416 V primary, 208Y/120 V secondary, and a ventilated, shielded design, this transformer supports reliable power delivery to critical loads. The WS34 weather shield adds outdoor durability, while UL Listed certification provides safety compliance. It is well-suited for data centers, manufacturing lines, and process facilities requiring stable voltage and EMI control.
The N43M28T49X is UL Listed, indicating compliance with established safety standards for electrical equipment. This certification supports regulatory acceptance in many markets and simplifies procurement for safety-conscious projects. Buyers should verify regional requirements, as additional certifications may be pursued locally, depending on application location and regulatory context.
Expect reliable lifecycle performance driven by a robust ventilated design, shielded construction, and a durable WS34 weather shield, reducing maintenance frequency and downtime. The Eaton warranty (25-000) provides a clear post-sale safety net. While precise ROI depends on site loads and energy prices, improved voltage regulation, reduced EMI, and longer service life typically translate to lower operating costs and higher uptime.
