FAQs
When installing the S20N11S05S6, verify the panel space accommodates its 9.89 in depth, 16 in height, and 10.38 in width. Plan for a stable mount to support the 148 lb weight and ensure adequate ventilation or enclosure cooling. Use the 3A wiring connection as specified and follow enclosure notes for Grade 316 stainless steel options without implying a NEMA 4X rating.
The transformer operates at 60 Hz, is single-phase, and has a primary voltage of 240 V or 480 V with a secondary of 120/240 V. It is rated for 5 kVA, suitable for supplying control circuits and automation equipment with varying load demands. The 115 °C rise indicates solid insulation margins for confined spaces and higher ambient temperatures.
Yes, the unit is designed for indoor-outdoor use and is specified with a Weathershield rating of Indoor-Outdoor. For enhanced corrosion resistance, a Grade 316 stainless steel enclosure option is noted (does not guarantee NEMA 4X). This makes it suitable for exposed plant floors, canteens, or outdoor equipment enclosures when installed per Eaton guidance.
Certifications can vary by region. The catalog notes indicate Certifications: Contact Manufacturer, so it is essential to consult Eaton documentation or your regional sales engineer to confirm CE, IP, or other regulatory approvals applicable to your installation site.
With a 5 kVA rating and aluminum coil design, the transformer offers efficient operation and potentially lower operating costs due to lighter weight and reduced copper usage. A one-year warranty from installation (or 18 months from shipment) helps protect initial investment, while the robust enclosure and 60 Hz single-phase performance minimize maintenance and replacement frequency in automation applications.
