FAQs
What mounting and clearance requirements apply when integrating the Eaton S20N11S07CUSS4X in a standard control panel? The unit features a 1784X frame and a NEMA 4X enclosure, so plan for adequate front-access clearance, proper mounting rails, and ventilation to maintain the 150 °C rise rating. Use copper windings to minimize copper losses and ensure correct primaries wired for 240/480 V input and 120/240 V output, with consideration for indoor-outdoor service use.
The transformer supports 240 V and 480 V primary voltages with a 120/240 V secondary output and a 7.5 kVA VA rating at 60 Hz single-phase operation. Copper windings provide reliable performance, and the 150 °C rise rating indicates robust thermal capability for continuous operation in demanding environments.
Yes. The enclosure is rated NEMA 4X with a 304 stainless steel build, designed for indoor-outdoor service. This makes the unit appropriate for applications from climate-controlled panels to areas with exposure to moisture or cleaning processes, simplifying placement decisions and reducing enclosure swaps.
Certifications are listed as Contact Manufacturer, so verify availability of UL/CE documentation and performance datasheets through Eaton. You can access the specification sheet and the catalog notes to confirm regulatory alignment, installation guidelines, and warranty coverage, ensuring compliance with your internal procurement standards.
Copper windings and a robust NEMA 4X enclosure support long service life with low resistance losses, aiding energy efficiency. Indoor-outdoor capability reduces the need for additional protection, lowering upfront enclosure costs. The 7.5 kVA rating provides just-right capacity to minimize oversizing, helping reduce capital and operating expenses over the asset lifecycle.
