Copper windings provide robust electrical performance, reducing energy losses and improving thermal management, which translates to higher efficiency and cooler operation in continuous-duty control circuits. This supports longer equipment life and lower energy costs in high-demand automation lines, while enabling smoother startup for motor drives and logic panels. Epoxy encapsulation (EP) delivers moisture resistance and vibration damping, minimizing insulation failures in harsh environments and reducing maintenance intervals. The 179 frame with 513G wiring simplifies enclosure layout and field wiring, enabling faster, error-free installations and easier retrofit projects in aging facilities. The NEMA 3R enclosure and indoor-outdoor rating expand site placement options, from covered rooms to exterior cabinets, without sacrificing safety or performance. Electrostatic shielding further reduces EMI interference with nearby sensors and PLCs, improving measurement accuracy and process control. The 60 Hz, single-phase, 480 V primary and 120/240 V secondary config supports standard control power needs across multiple machines, while the 115 °C rise rating provides a healthy thermal margin for continuous operation. Overall, this unit combines rugged construction with precise voltage transformation, delivering reliable automation power with lower life-cycle costs and simplified maintenance.

FAQs
For optimal results, mount the transformer in a ventilated enclosure or within a dedicated control panel that accommodates its 230 lb weight and 13.38 in width, 19 in height, and 10.52 in depth. Use appropriate mounting hardware for the 179 frame, ensure 480 V primary supply is available, and route 513G wiring cleanly to minimize EMI and maintenance access constraints.
Key specs include a 10 kVA rating, 60 Hz frequency, single-phase configuration, 480 V primary, 120/240 V secondary, copper windings, 115 °C rise, and a copper-wound, electrostatically shielded design. The unit is UL Listed and designed for indoor-outdoor (NEMA 3R) service, making it suitable for comprehensive control power in automated systems.
Yes. The transformer features a NEMA 3R enclosure and indoor-outdoor compatibility, so it can be installed in exposed or semi-exposed locations. The epoxy encapsulation provides moisture resistance and vibration damping, while the electrostatic shielding minimizes EMI, helping maintain sensor and PLC reliability in challenging facilities.
This transformer is UL Listed, indicating compliance with recognized safety standards. It is designed for indoor-outdoor use (NEMA 3R) and uses copper windings for reliable electrical performance. The combination of these features supports regulatory compliance in many industrial environments and helps streamline procurement and commissioning.
The 10 kVA rating supports reliable control power for multiple devices with lower risk of voltage drop, while copper windings improve efficiency and reduce heat-related losses. The rugged enclosure and EMI shielding reduce maintenance and downtime, translating to lower life-cycle costs, fewer failures, and quicker project ramp-ups for automation initiatives.
