Eaton T57M11S10ZZ Open-core transformer - 10 KVA

Open-core ventilated design enhances heat dissipation, reducing thermal rise under steady loads and allowing longer duty cycles without derating. This approach shifts reliability from a thermal bottleneck to an expected operating envelope, enabling longer maintenance intervals and fewer cooling challenges in crowded cabinets. For engineers, this means you can pack more intelligence and sensing into a single panel without sacrificing performance. The design is well suited to dense control panels and machine enclosures where airflow is critical and space is at a premium. Ten kilovolt-ampere rating with 1-phase operation supports typical industrial feeder requirements in automation and process lines. The 575 VAC input paired with dual 120/240 VAC secondary outputs simplifies wiring, reduces interconnection complexity, and improves fault tolerance in panel boards. This combination is ideal for powering PLCs, motor starters, relays, and field devices in factory automation while maintaining voltage stability even during loading surges. Ventilated transformer construction improves air circulation around windings, reducing hot spots and enabling stable performance across a wider range of ambient temperatures. The dual-secondary outputs offer flexibility for different loads and minimize copper runs in the field. For installation, Eaton provides mounting patterns, accessory options, and clearly mapped terminal assignments in the T57M11S10ZZ datasheet, helping you simplify procurement and lifecycle management. At 132 lb, this unit delivers robust mechanical strength for floor or cabinet mounting in industrial rooms, with vibration resilience suitable for heavy equipment environments. The open-core coil and ventilated cage design support easier service and reduced risk of winding damage during maintenance. Access to Eaton catalogs and the manufacturer datasheet accelerates commissioning and ensures consistent, repeatable installations across multiple lines. Note that certifications are listed as 'Contact Manufacturer' in the product data, so verify UL/CE compliance and environmental ratings through Eaton's official specification sheet and transformer catalogs. This documentation supports audit trails, regulatory alignment, and accurate BOMs during procurement and lifecycle planning.
