Eaton S20P11E02P General transformer - UL Listed
Part Number: S20P11E02P
Quick Summary
The Eaton S20P11E02P General purpose encapsulated transformer provides reliable single-phase power conversion for electrical panels and equipment in industrial settings. This compact, epoxy-encapsulated unit supports indoor-outdoor installations with a rugged NEMA 3R enclosure, helping reduce field maintenance and downtime. Its UL Listed certification reinforces safety and compliance in regulated environments, while the electrostatically shielded winding minimizes EMI in sensitive control circuits. Voltage flexibility is a key business advantage: a 2 kVA rating with multiple primary tap options supports supply variations without sacrificing performance. By combining robust construction with easy installation, it lowers total cost of ownership for panel builders and integrators, while enabling safer, more predictable voltage delivery for downstream devices.

Encapsulated construction with electrostatic shielding provides EMI suppression and moisture resistance, translating to longer life in variable plant environments and reduced equipment failures in control panels. This directly lowers maintenance costs and unplanned downtime when panels operate in near-humidity or outdoor locations. The NEMA 3R enclosure enables indoor-outdoor installations, expanding site options and simplifying mounting in cramped or harsh environments while preserving safety margins for school, hospital, or manufacturing environments. Tap settings offer voltage regulation flexibility; 1 at +5% FCAN, 2 at -5% FCBN × 2 at +2.5% FCAN, 4 at -2.5% FCBN, enabling voltage compensation to maintain downstream device performance amidst supply fluctuations, reducing nuisance trips and improving process stability. The 2 kVA, single-phase design delivers ample headroom for distribution to lighting, control relays, and small motors, optimizing footprint in switchgear and panel boards. Aluminum windings reduce weight and thermal stress, contributing to easier handling during installation and robust operation in temperature-varied facilities. The 115 °C rise rating and UL Listed certification reinforce reliability and regulatory compliance, supporting predictive maintenance programs. Overall, this transformer is well-suited for compact control panels and distributed power applications where ruggedness, reliability, and ease of integration drive ROI.

FAQs
This transformer uses a NEMA 3R enclosure designed for indoor-outdoor use, so install in a protected area with adequate airflow and clearance for heat dissipation. Ensure proper mounting, secure cable entries, and compliance with local electrical codes. Consider rain exposure, wind, and dust when selecting mounting orientation, and use proper strain relief on all connections.
The S20P11E02P features 240 V or 480 V primary voltage options and provides a 120/240 V secondary output. This configuration supports common industrial distribution needs, enabling you to power control circuits and small machinery from standard mains without additional voltage conversion equipment.
The transformer includes a taps scheme: 1 at +5% FCAN, 2 at -5% FCBN, two at +2.5% FCAN, and four at -2.5% FCBN. These taps allow fine adjustment to counteract supply fluctuations, ensuring downstream devices receive stable voltage, reducing overheating and nuisance tripping, and improving process consistency in variable grid environments.
The S20P11E02P is UL Listed, confirming safety compliance for industrial equipment. Its NEMA 3R enclosure supports outdoor-rated installation. While specific CE or IP certifications are not listed in the provided data, the UL Listing combined with indoor-outdoor suitability covers key regulatory and environmental requirements for many North American facilities.
