Indoor-Outdoor
Powerful and compact, the S20K11S07SS4X delivers 7.5 kVA of single-phase power, converting from 240/480 V primary to a 120/240 V secondary. Designed for control panels and machine automation, it minimizes voltage drop and supports precision devices like PLCs and drives. Aluminum windings reduce weight, improve efficiency, and simplify field service, lowering total ownership costs. A robust design supports continuous operation in demanding industrial environments while maintaining margin for startup surges. Enclosed in a NEMA 4X rated stainless steel housing, the transformer withstands washdown, moisture, and corrosion. The indoor-outdoor Weathershield configuration adds durability where outdoor installations are required. Catalog notes specify a NEMA 4X Grade 304 stainless steel enclosure for corrosion resistance. This protection translates to longer service life and fewer maintenance cycles in harsh environments. Tap size is 1 at -10% FCBN and 2 at -5% FCBN, enabling voltage regulation to compensate for supply fluctuations. This feature reduces risks of under- or over-voltage conditions that could affect sensitive equipment. Users can fine-tune output to meet control-tolerance requirements without replacing the transformer. Operating at 60 Hz and single-phase, the unit aligns with typical US industrial power systems. Secondary voltage is 120/240 V, suitable for logic circuits, sensors, and control relays. The primary voltage supports both 240 and 480 V inputs, while the 7.5 kVA rating covers mid-range loads. Dimensions are 9.89 in length, 10.38 in width, and 16 in height, offering a compact footprint. Compact size combined with aluminum windings simplifies mounting in standard electrical cabinets. Compatibility with common panel designs reduces retrofitting time and accelerates commissioning. The warranty provides one year from installation or 18 months from shipment, whichever occurs first. This coverage, along with Eaton's service network, helps minimize downtime and maintenance costs. For mission-critical applications, predictable performance supports uptime and warranty-backed reliability.

FAQs
Install the S20K11S07SS4X in a suitably rated enclosure, ensuring proper clearance for cooling and wiring. Connect the 240/480 V primary to supply lines and bring 120/240 V outputs to the control circuits or PLCs. Use the -10% and -5% tap settings to fine-tune output, and secure the unit with appropriate mounting hardware per the enclosure’s dimensions (9.89 in L x 10.38 in W x 16 in H).
Key specs include a 7.5 kVA VA rating, single-phase operation at 60 Hz, primary voltage 240/480 V, secondary voltage 120/240 V, and aluminum windings. Tap changers are 1 at -10% FCBN and 2 at -5% FCBN. The enclosure is NEMA 4X rated for indoor-outdoor use, with a 150 °C rise rating for robust performance.
Yes. The S20K11S07SS4X comes with a NEMA 4X Grade 304 stainless steel enclosure, designed for indoor-outdoor service and resistance to moisture and corrosion. Its Weathershield configuration and corrosion-resistant housing make it well-suited for outdoor installations or washdown areas typical in industrial facilities.
Certification details are listed as manufacturer-confirmation only, but the enclosure meets NEMA 4X protection and stainless steel construction. This supports compliance with corrosion resistance and environmental protection standards commonly required for industrial transformers in demanding settings.
The unit carries a one-year warranty from installation or an 18-month warranty from shipment, whichever comes first. Together with Eaton’s service network, this reduces downtime and maintenance costs by ensuring predictable performance and access to support during the equipment lifecycle.
