FAQs
Plan for a compact footprint using the 9.89 in L × 10.38 in W × 16 in H enclosure and connect 3M wiring leads. Mount the transformer on a stable panel surface, route primary 240/480 V and secondary 110/220 V conductors to designated terminals, and ensure clearances for heat dissipation and service access.
Confirm 5 kVA rating, single-phase configuration, primary voltages of 240 V and 480 V, secondary voltages of 110/220 V, frequency 50–60 Hz, and a temperature rise of 115 °C. Check aluminum coil construction and NEMA 3R enclosure suitability for your environment.
Yes. The transformer features a NEMA 3R enclosure and an indoor-outdoor rating, enabling installation in semi-exposed environments. This reduces the need for additional weather protection and simplifies site planning in facilities with outdoor or partially protected spaces.
It is UL Listed and CSA Certified, signaling compliance with safety and quality standards. These certifications support regulatory acceptance in many regions and help streamline procurement for regulated industries, while the enclosure rating further reinforces reliability in harsh environments.
The unit carries Eaton’s warranty policy, one year from installation or eighteen months from shipment, whichever occurs first. This, combined with robust construction and long service life, reduces downtime costs and strengthens return-on-investment for critical automation and power-distribution applications.
