Eaton S20N11P26S64X General-Purpose Transformer - NEMA 4X
Part Number: S20N11P26S64X
Quick Summary
Eaton general-purpose encapsulated transformer provides safe single-phase voltage conversion for control panels. Engineers struggle with space, corrosion, and weather exposure in harsh environments, but the NEMA 4X, 316 stainless enclosure helps protect critical power conversions. It’s suited for automation panels, machine builders, and panel shops seeking durable, 0.25 kVA transformers with rugged construction. The copper windings, 60 Hz operation, and 240/480 V inputs to 120/240 V outputs support reliable control power. This translates to reduced downtime, easier maintenance, and predictable sourcing for procurement teams. Its copper windings and 60 Hz, 0.25 kVA rating support efficient, reliable power for PLCs and drives.

FAQs
Plan mounting using the 57P4X frame with a rigid surface. Ensure the NEMA 4X enclosure remains intact and accessible for servicing. Connect the primary to 240/480 V as appropriate and wire the secondary to 120/240 V circuits, observing clearance, ventilation, and any local electrical codes.
It delivers 0.25 kVA of single-phase power at 60 Hz, converting 240/480 V to 120/240 V with copper windings for efficiency. Its encapsulated, compact design simplifies panel layouts, reduces mounting footprint, and provides stable PLC and relay power in tight automation cabinets, supporting reliable machine operation and easier maintenance.
The transformer uses a rugged NEMA 4X enclosure and is built with a 316 stainless steel grade per catalog notes for indoor-outdoor service. Formal third-party certifications are listed as 'Contact Manufacturer,' so verify CE or other regulatory marks with Eaton as required for your project.
Primary voltage is 240 V or 480 V, secondary voltage is 120/240 V, operating frequency is 60 Hz, and the unit is rated at 0.25 kVA with copper windings. It supports a 115 °C rise in ambient conditions and is designed for indoor-outdoor use with a NEMA 4X enclosure and 57P4X frame.
The 316 stainless steel enclosure provides corrosion resistance for wash-down and outdoor environments, reducing maintenance cycles. Copper windings offer high efficiency, while Eaton’s warranty policy provides one-year coverage from installation or 18 months from shipment, aiding budgeting and asset management for ongoing production.
