Eaton S20P11S10CUSS4X General-Purpose Transformer - NEMA 3R
Part Number: S20P11S10CUSS4X
Quick Summary
Eaton General purpose encapsulated transformer delivers reliable power isolation for control panels and industrial equipment. In demanding facilities, unsealed or undersized transformers cause unplanned downtime and costly field rework. UL Listed certification and a rugged NEMA 3R enclosure provide safe operation indoors or outdoors, even in dusty or damp environments. The unit's 10 kVA rating with copper windings supports scalable power distribution, while 240/480 V primary and 120/240 V secondary voltages align with standard plant wiring. Designed for ease of installation, the encapsulated EP design and accessible tap settings simplify maintenance and future expansion.

FAQs
Install on a rigid, vibration-free base inside a compliant enclosure. Use the NEMA 3R-rated enclosure for indoor-outdoor environments, connect primary windings to 240 V or 480 V as needed, and wire the 120/240 V secondary to the load. Ensure proper grounding and verify the tap settings match your supply voltage under load.
The transformer is a 10 kVA, single-phase unit with 60 Hz frequency. Primary voltages are 240 V and 480 V, secondary voltage is 120/240 V, copper windings are used, and it has a 115 °C rise. It features multiple tap settings and a NEMA 3R enclosure rated for indoor-outdoor use.
Yes. It uses a NEMA 3R enclosure designed for indoor-outdoor service and UL Listed safety certification, making it well-suited for rugged control panels, machine rooms, and outdoor equipment exposed to dust, moisture, or temperature variation.
This model is UL Listed, ensuring compliance with recognized safety standards. The NEMA 3R enclosure rating further confirms suitability for outdoor and semi-protected installations, improving reliability and simplifying regulatory acceptance in industrial facilities.
Copper windings and robust encapsulation minimize heat and insulation wear, extending service life. The 10 kVA rating supports multiple loads from a single transformer, reducing footprint and installation costs, while voltage tap settings help maintain equipment performance, reducing maintenance downtime and energy waste.
