FAQs
This model is a three-phase, 480 V primary to 208Y/120 V secondary transformer. Wiring is specified as 283B, and the unit’s dimensions (51 in high x 34.5 in wide x 31.5 in deep) plus a 1200 lb weight should be matched to a compatible electrical room. The generic footprint supports common rack and room layouts, simplifying siting and mounting for automation and switchgear enclosures.
The transformer carries UL Listed certification and meets DOE2016 Efficient standards, delivering lower energy losses and safer operation across duty cycles. These protections help with regulatory compliance, reduce energy costs over the equipment’s life, and provide assurance for audits and facility commissioning.
Applications with high short-term loading and heat sensitivity—such as data centers, automation cells, and critical manufacturing lines—benefit from improved heat dissipation and reduced temperature rise. The K-Factor design helps manage harmonic-related losses and supports reliable performance in dense electrical rooms and switchgear assemblies.
Plan for a 51 by 34.5 by 31.5 inch footprint and 1200 lb weight, ensuring appropriate floor loading and clearances. The standard 283B wiring aids quick integration with existing panels, while the DOE2016 efficiency and UL Listed status contribute to lower operating costs and smoother regulatory approvals during commissioning.
Verify a 480 V primary and 208Y/120 V secondary within three-phase electrical distribution. Confirm the 112.5 kVA rating and the 150 °C temperature rise compatibility with your equipment’s load profile. The unit’s frame 943 and 112.5 kVA rating align with standard industrial transformer inventories and ensure reliable control power for drives and panels.
