Eaton S27N11S03N Encapsulated Transformer - UL Listed

Encapsulated construction provides rugged protection for the power path, guarding windings and insulation from dust, moisture, and incidental contact in demanding environments. The aluminum coil reduces weight and improves heat dissipation versus pure copper designs, enabling a compact, efficient package without compromising thermal performance. In a 60 Hz, single-phase system rated at 3 kVA, it delivers dependable control power to panels and automation hardware while maintaining headroom for startup surges and transient loads common in machine tools and conveyors. This robust design is well-suited for both new installations and retrofit projects where space is at a premium and reliability is non-negotiable.\n\nNEMA 3R enclosure adds indoor-outdoor resilience, so dependable operation continues from a guarded panel in a factory to a weather-exposed machine in a manufacturing line. UL Listed certification supports safety compliance during audits and procurement, smoothing supplier qualification and customer validation across regulated industries. The combination of enclosure protection and stringent safety certification reduces field service events and increases uptime in critical production lines, while simplifying risk management for regulated environments.\n\nMechanical footprint and connection simplicity support fast, error-free installation and easier future upgrades. With 8 inches depth, 7.69 inches width, and 14.25 inches height, it fits standard control cabinet layouts while leaving room for wiring harnesses, relays, and other devices. A 524A wiring connection standardizes terminations, enabling repeatable, scalable installations across multiple machines and lines.\n\nElectrical compatibility: the unit bridges 277 V primary to 120/240 V secondary, meeting common automation and control schematics without requiring a separate ACDC converter or inrush management. The 3 kVA rating offers a healthy margin for moderate loads and startup transients, contributing to improved system reliability and reduced nuisance trips in automated conveyors and robotics.\n\nWarranty and service: Eaton policy 25-000 provides one year from installation or eighteen months from shipment, whichever occurs first, with long-term support through spare parts and technical assistance. This warranty, combined with Eaton''s engineering resources and global service network, helps protect your investment, shorten downtime, and optimize total cost of ownership in mission-critical applications.
