Feature: 5 kVA general-purpose encapsulated transformer. Impact: Provides scalable, reliable power for mid-size loads while occupying a compact footprint, reducing the need for multiple devices and improving panel density. Application: Control panels, motor starters, and small MCCs in manufacturing environments benefit from a dependable, space-efficient solution. Feature: 60 Hz single-phase operation with 240 V input and 208 V output. Impact: Aligns with common North American distribution and equipment that requires 208 V, simplifying integration and stocking. Application: Upgrading legacy panels or new equipment lines that demand stable 208 V from a 240 V source. Feature: NEMA 3R indoor-outdoor enclosure. Impact: Weatherproof performance for outdoor and damp locations, reducing separate enclosures and field retrofit costs. Application: Outdoor switchgear, exterior panels, and difficult-to-secure plant corners in need of reliable protection. Feature: Tap settings 2 at +2.5% FCAN and 2 at -2.5% FCBN. Impact: Enables precise voltage regulation to compensate for supply swings and maintain critical loads within tolerance. Application: Sensitive controls and PLC interfaces that require tighter voltage control in fluctuating facilities. Feature: Aluminum winding with 115 °C rise. Impact: Lighter, cost-effective windings with ample thermal margin for continuous operation under load. Application: Continuous-duty use in harsh environments where heat buildup must be managed and maintenance minimized. Feature: 582D wiring and 177 frame footprint. Impact: Standardized mounting and wiring interfaces simplify installation and compatibility with Eaton accessories and replacement parts. Application: Retrofit projects and new builds where predictable fit and straightforward wiring streamline procurement and startup.

FAQs

For outdoor or damp locations, mount the unit in a compliant enclosure with ventilation appropriate to its 109 lb weight and 16 inch height. Utilize the 582D wiring interface and 177 frame footprint to ensure secure mounting. Maintain proper clearance for service access and follow supplier practices for UL Listed equipment to support safe, ongoing operation.
The S24D29S05 is a single-phase transformer with a 240 V primary and a 208 V secondary, designed for 60 Hz operation. It provides a 5 kVA rating, enabling stable stepping down for compatible equipment while supporting reliable panel power. This configuration is common in North American industrial environments.
This transformer is ideal for control panels, motor control centers, and distribution in manufacturing facilities. Its NEMA 3R enclosure supports indoor-outdoor deployment, making it suitable for outdoor switchgear or exterior panels. The voltage regulation and rugged design help maintain uptime in fluctuating power conditions.
The unit offers two positive taps at +2.5% and two negative taps at -2.5%, allowing fine-tuning of the secondary voltage to compensate for supply fluctuations. Use these taps when your loads require strict voltage stability or when line voltage drifts over time, ensuring equipment remains within tolerance without swapping transformers.
The transformer is UL Listed and features a NEMA 3R enclosure for indoor-outdoor use, enabling installation in varied environments. These certifications simplify compliance during procurement and commissioning, especially for facilities with strict safety or energy-management requirements.
