Eaton S26N11E03 Encapsulated Transformer - 3kVA

Encapsulated construction delivers environmental protection and safety benefits. The sealed winding enclosure guards against moisture, dust, and incidental contact, which translates to higher reliability in harsh industrial settings and safer handling during installation. For panel builders and OEMs, this means fewer field failures and reduced warranty risk, while maintaining compliance with general-purpose transformer standards. The 3 kVA, single-phase configuration provides robust auxiliary power for sensors, relays, and control circuits without oversizing, lowering initial cost and simplifying upstream wiring. The 115°C rise rating indicates solid thermal performance under typical loads, enabling stable operation in compact cabinets and busy automation lines. This combination reduces cooling requirements and supports longer service intervals, contributing to lower total cost of ownership. The encapsulated form also eases maintenance planning by limiting moisture ingress and vibration-related wear, which is especially valuable in repetitive startup/shutdown cycles common in manufacturing environments. Compatibility with standard control-power architectures ensures straightforward integration with existing panels, wiring harnesses, and safety interlocks, while the compact footprint helps maximize enclosure real estate for other critical components. In practice, engineers gain predictable behavior, easier documentation, and faster commissioning when deploying the S26N11E03 in new or retrofit projects.
