FAQs
For panel installations, verify the 240/480 V primary and 120/240 V secondary wiring, ensure adequate clearance for the NEMA 4X enclosure, and plan for 60 Hz operation. The unit’s copper windings and encapsulated design support compact layouts, while the selectable taps allow voltage tuning to maintain stable downstream voltages under fluctuating loads.
Confirm 25 kVA VA rating, single-phase configuration, 60 Hz frequency, primary 240/480 V, secondary 120/240 V, and the tap sizes: 1 at +5% FCAN, 2 at -5% FCBN, plus 2 at +2.5% FCAN and 4 at -2.5% FCBN. Also note the 150 °C rise rating and copper coil construction for reliability in industrial environments.
Yes, the S20P11S25CUS64X is designed for indoor-outdoor use with a NEMA 4X enclosure and 316 stainless steel construction per catalog notes. This combination provides corrosion resistance and protection against environmental exposure, making it suitable for outdoor panels and process areas while maintaining safety and performance.
Certifications are listed as Contact Manufacturer. While specific SIL, CE, or IP ratings aren’t published here, refer to Eaton’s datasheet and catalog notes for enclosure protection details and request formal certification documentation from Eaton to confirm regulatory compliance for your site requirements.
Expect improved reliability from copper windings and a rugged encapsulated design, which reduces maintenance frequency in tough environments. The 25 kVA rating supports mid-range industrial loads with stable voltage, contributing to lower downtime, longer equipment life, and a faster payback in automation and control-system upgrades.
