Eaton S20L11S37CUSS encapsulated transformer - 37.5 kVA

Copper windings and a robust encapsulated design deliver efficient energy transfer and superior thermal stability under demanding industrial loads, reducing hotspots in dense control networks. That translates to lower operating losses, longer component life, and minimized unplanned downtime for critical automation circuits in harsh environments. Operators gain predictable performance across fluctuating loads, enabling tighter process control, easier preventive maintenance, and smarter asset retirement planning for long-term plant reliability. At 37.5 kVA, with a 240/480 V primary and 120/240 V secondary, the unit supports common industrial architectures at 60 Hz, providing a versatile power path for diverse lineups. This compatibility reduces the need for adapters or rewiring during panel upgrades, simplifies procurement for multi‑voltage sites, and accelerates commissioning in retrofit projects. Voltage taps provide precise regulation: two at -5% FCBN and four at -2.5% FCBN, enabling compensation for supply drift across typical plant tolerances. Copper windings and a 248A wiring connection support dependable performance under elevated loading, minimizing voltage sag during motor start‑ups and peak demand periods. These features reduce nuisance tripping, improve motor and PLC responsiveness, and simplify commissioning for new installations and retrofits. The enclosure uses Grade 304 stainless steel noted in catalog information to offer corrosion resistance for indoor‑outdoor applications and challenging humidity levels. Although the catalog specifies this does not imply a NEMA 4X rating, the rugged construction aligns with semi‑exposed installations and harsh factory environments. With a footprint around 14 by 22 by 28 inches and an 867 lb weight, installation teams can plan solid mounting, easy service access, and safe maintenance. Warranty coverage includes one year from installation or eighteen months from shipment, whichever comes first, backed by Eaton's global support network. Together with the available specification sheet, this supports regulatory alignment, predictable maintenance, and a clear ROI for mission-critical automation assets.
