Special features
K13
DOE2016 efficiency and UL listing are integral design features. The result is lower transformer losses in loaded and unloaded states, which translates into cooler operation and reduced cooling costs in manufacturing floors. This is especially valuable for continuous-load applications where energy spend is ongoing and reliability is critical. The 112.5 kVA three-phase rating enables scalable power distribution for equipment clusters, reducing the need for multiple smaller transformers and optimizing panel space. K13 cooling and the 115 °C rise support reliable operation under harmonically rich loads common in modern production lines. Wiring connection 283B and the 943 frame simplify integration with existing switchgear and enclosures, easing on-site installation and commissioning. At 1200 lb with precise dimensions, the unit offers a rugged, serviceable platform that minimizes downtime during maintenance and upgrades.

FAQs
The transformer is designed with a 480 V primary and a 208Y/120 V secondary. This three-phase configuration supports common industrial power distribution needs, enabling equipment rated for 480 V to operate reliably on a standard 208Y/120 V secondary distribution network.
Yes. The unit meets DOE2016 efficiency requirements and carries UL Listed certification, ensuring both energy performance and safety compliance for industrial installations. These features support regulatory alignment, reduce energy waste, and simplify audits on site.
Key specs include 112.5 kVA rating, 480 V primary, 208Y/120 V secondary, and a temperature rise of 115 °C. Physical size is 34.5 in W x 51 in H x 31.5 in D with a weight of 1200 lb, and wiring connection 283B. Plan for adequate clearance and ventilated space per enclosure requirements.
Wiring connection 283B and the frame 943 are designed for straightforward mounting in standard electrical rooms. Ensure compatibility with existing switchgear, allow for proper ventilation, and maintain access for servicing. The footprint and weight necessitate secure, floor-mounted installation with appropriate seismic and mechanical support per local code.
Ideal for industrial power distribution where harmonic loads are common, such as manufacturing lines, machine centers, and data-center feeder panels. The 112.5 kVA three-phase rating, DOE2016 efficiency, and UL safety certification help reduce energy costs, improve reliability, and support scalable expansion without multiple smaller transformers.
