DOE2016 efficiency and K-Factor design reduce core and winding losses, delivering measurable energy savings and cooler operation. This directly lowers cooling requirements and extends equipment life, particularly in continuous-operation environments such as data centers and automated manufacturing lines. Three-phase, 150 kVA rating with a 480 V primary and 208Y/120 V secondary enables seamless integration with standard industrial power systems. M-Taps provide voltage regulation options to match load variations, while the 150 °C temperature rise margin supports reliability in confined electrical spaces and hot climates. UL Listing and K13 features address safety, traceability, and compliance with electrical standards in plant environments. The 283B wiring connection and 943 frame facilitate installation in existing enclosures or retrofit projects. The ventilated design reduces heat buildup and cooling energy, improving lifecycle costs and reducing fan wear in demanding plants. Compatibility with 480 V to 208Y/120 V distribution makes it ideal for control panels, machine tooling, and process automation in harsh industrial environments. Industry insights show K-Factor devices excel with non-linear loads such as drives and rectifiers, minimizing overheating, voltage drift, and maintenance events.

FAQs
For new panel installations, ensure the enclosure can accommodate a 31.5 in depth, 34.5 in width, and 51 in height unit. Plan for 283B wiring connections, proper clearance for ventilation, and room for the 150 °C rise margin. Verify 480 V input, 208Y/120 V secondary distribution, and M-Tap voltage regulation options to minimize voltage drift under load peaks. Consider UL-listed compliance and K13 features to meet safety and reliability standards.
Expect robust, continuous three-phase power with strong regulation under typical industrial loads. The 150 kVA rating supports sizable motor drives, controls, and automation equipment, while the 480 V to 208Y/120 V configuration aligns with common plant distribution schemes. DOE2016 efficiency reduces losses, and the K-Factor design helps manage non-linear loads without overheating, improving overall system reliability and lifecycle costs.
Yes. The N48M28T4921CULS50 is specified as DOE2016 Efficient and UL Listed, aligning with contemporary regulatory expectations for energy performance and safety. These certifications support compliance in industrial facilities, OEM integrations, and control-room installations, reducing risk during audits and ensuring safe operation under continuous-duty conditions.
Absolutely. M-Taps provide voltage adjustment options to respond to load changes, helping stabilize supplies to critical equipment. The 150 °C rise rating offers a healthy margin for heat management in dense installations, enabling reliable operation in less-than-ideal cooling environments and helping prevent derating of connected devices during peak loads.
The DOE2016 efficiency and ventilated design translate into lower energy and cooling costs over the life of the unit, generating a favorable ROI in facilities with continuous operation. UL certification and K13 features simplify maintenance planning, while reduced heat and improved reliability lower failure-related downtime. The M-Taps along with a robust frame and wiring connection streamline installation and future upgrades, further enhancing total cost of ownership.
