Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated construction with aluminum windings protects windings from moisture and dust, reducing maintenance and extending transformer life. This yields lower downtime and fewer service calls for industrial automation panels where reliability matters most. The design is ideal for control cabinets and machine panels in harsh environments, delivering consistent performance across varying temperatures. Outdoor-ready resilience comes from a NEMA 3R enclosure and Weathershield rating, enabling indoor-outdoor installation without special housing. With a 5 kVA rating and 60 Hz single-phase operation, it delivers steady control power for mid-size machines and panelboards, stepping down from 480 V to 230 V for control circuits. Wiring is simplified by the 511AR configuration, allowing straightforward terminations and quick field setup. The transformer operates with a 115 °C rise, balancing thermal performance with a compact footprint for reliable voltage regulation under load. UL Listed safety certification supports compliance, while its dimensions (9.89 in depth, 16 in height, 10.38 in width) and a 114 lb weight ease enclosure integration and handling. Warranty coverage aligns with Eaton policy 25-000, offering protection from installation or shipment dates, reinforcing long-term support and service maintenance readiness. This blend of rugged design and standard industry interfaces reduces procurement risk and accelerates project timelines in control power applications.
