Eaton Specification Sheet - N48M22T49EE
Feature → Business Impact → Application: K-Factor nonlinear design reduces harmonic distortion and stabilizes voltage under varying load conditions, improving downstream equipment performance and extending motor life in heavy manufacturing lines. Application: Three-phase power networks in stamping, packaging, and process facilities that experience load swings benefit from tighter regulation and reduced maintenance costs. Feature → Business Impact → Application: Tap settings with 2 at +2.5% and 4 at -2.5% enable precise voltage shaping, which minimizes voltage drop and improves efficiency across critical loads. Application: Facilities with long feeders or multi-stage machines where supply voltage fluctuates will see fewer nuisance trips and smoother operation. Feature → Business Impact → Application: Aluminum coil construction plus 150 kVA rating delivers strong balance of durability and weight, enabling easier installation in constrained spaces while handling substantial load demands. Application: Mid-size distribution cabinets and switchgear rooms in manufacturing floors and data centers. Feature → Business Impact → Application: Electrostatic shielding reduces EMI, supporting sensitive controls and PLCs in noisy industrial environments. Application: Robot cells and automation lines requiring clean control signals without interference. Feature → Business Impact → Application: Weathershield WS34 and 60 Hz three-phase design ensure reliability in varied environments, with compliant insulation and temperature rise up to 150 °C, enabling longer service intervals. Application: Outdoor or semi-protected installations and harsh factory floors where ambient conditions are challenging. Feature → Business Impact → Application: UL Listed and NEMA TP-1 compliant status lowers procurement risk and accelerates compliance documentation. Application: Compliance-driven projects in automotive, food & beverage, and general manufacturing seeking documented conformance.

FAQs
Plan for a three-phase, 480 V input with a 240 delta/120 midtap secondary. Check space for the 24.67 in L, 31.44 in W, 56.17 in H footprint and anticipate a 1249 lb weight. Use the WS34 weather shield if installed outdoors and ensure clearance for heat dissipation and access to taps (+2.5% / -2.5%).
It is a 150 kVA, three-phase transformer with a 480 V primary and 240 delta/120 midtap secondary, rated for 60 Hz. It features taps at +2.5% and -2.5%, aluminum coil construction, 150 °C rise with a 200 °C insulation system, and is UL Listed with NEMA TP-1 compliance.
Yes. It is UL Listed and NEMA TP-1 compliant, with catalog notes indicating efficiency and an electrostatic shield. These certifications support regulatory compliance in manufacturing, automotive, and distribution environments while enabling smoother audits and procurement processes.
Applications with variable loads and significant harmonics, such as stamping presses, conveyors, and automated assembly lines, benefit from improved voltage regulation and reduced harmonics. The 480 V to 240/120 V secondary setup supports diverse control systems and automation panels.
With a robust 150 kVA rating, electrostatic shielding, and weather protection, maintenance cycles are extended and downtime is reduced. The Eaton warranty offers one year from installation or 18 months from shipment, and UL/NEMA TP-1 compliance reduces regulatory risk while improving energy efficiency and long-term reliability.
