Eaton Specification Sheet - N43M28T45X
K-Factor nonlinear ventilated design is optimized to manage thermal rise under transient loads, reducing cooling energy and prolonging transformer life. Business impact: lower operating temperatures and improved uptime in continuous process environments; application: factory floors, packaging lines, and automated cells benefit from steadier voltage profiles. Aluminum windings reduce weight and material cost while maintaining electrical performance, improving ease of handling during installation and servicing; business impact: lower labor costs and inventory footprint. Electrostatic shielding adds fault isolation, enhancing protection for nearby control electronics and reducing EMI risk; application: critical automation panels in data centers and manufacturing facilities. The 2 at +2.5% FCAN and 4 at -2.5% FCBN tap settings provide voltage regulation to maintain secondary voltage within tolerance, even with input variations; impact: tighter voltage control translates to safer motor starting and longer equipment life. Three-phase 416 V primary and 208Y/120 V secondary, 50–60 Hz operation, and a 150 °C rise enable compatibility with standard industrial power architectures; application: new builds and upgrades in distributed power systems. The 45 kVA rating, frame 914D, and dimensions (22 in L × 29 in W × 39 in H) with a 535 lb weight support easy placement in existing enclosures and racks; impact: faster installation, fewer structural changes, and scalable capacity. Weathershield WS39 adds outdoor or harsh-environment resilience, while UL Listed certification provides safety assurance for plant-wide compliance and procurement endorsements.

FAQs
The N43M28T45X is a three-phase transformer designed around the 914D frame, with dimensions of 22 in L, 29 in W, and 39 in H and a weight of 535 lb. It supports floor-mounted or rack-style installation in standard electrical rooms or equipment enclosures. Consider clearance for ventilation and the WS39 weather shield if installed in outdoor or semi-outdoor spaces. Ensure mounting hardware and service clearances meet OEM and local code requirements for safe operation and future servicing.
Key specs include a 45 kVA rating, three-phase configuration, primary voltage of 416 V, secondary voltage of 208Y/120 V, and a frequency range of 50–60 Hz. The unit provides two taps at +2.5% FCAN and four taps at -2.5% FCBN to regulate secondary voltage. Temperature rise is rated at 150 °C, and windings are aluminum with electrostatic shielding to enhance safety and performance across typical industrial loading.
Yes. With a 45 kVA rating and a stabilized 208Y/120 V secondary, it supports essential power distribution needs in data centers and factory automation panels. The K-Factor nonlinear design helps manage loading harmonics, while the ventilated construction improves thermal performance in continuous operation. Its UL Listed safety certification, frame compatibility, and shielding features make it a reliable choice for mission-critical environments.
The N43M28T45X carries UL Listed certification, indicating compliance with recognized safety standards for electrical equipment. This supports safer installation, maintenance, and procurement in regulated facilities. Note that other certifications (for example CE or IP ratings) are not listed in the provided data; verify project requirements and supplier documentation for any additional compliance needs.
Expect straightforward maintenance benefits from its robust, aluminum-windings design, electrostatic shielding, and ventilated construction, which collectively reduce thermal stress and downtime. The warranty terms specify one year from installation or eighteen months from shipment, whichever occurs first, providing early-tier risk mitigation. The combination of reliable performance, easy installation with a standard 914D frame, and a strong safety profile supports a favorable total cost of ownership in manufacturing and data-center environments.
