FAQs
Install the S20K11E10 on a solid wall surface using the provided mounting hardware, ensuring adequate ventilation and clearance for heat dissipation. Route primary and secondary conductors per the 21A wiring specification, keep conductors shielded as recommended, and verify correct 240/480 V primary and 120/240 V secondary connections. Maintain the indoor-outdoor NEMA 3R rating through proper enclosure protection and avoid physical damage.
Key specs include a 10 kVA rating, 60 Hz frequency, single-phase operation, primary voltage options of 240 V and 480 V, secondary voltage of 120/240 V, and a wiring connection rating of 21A. Insulation is rated at 180 °C with a temperature rise of 115 °C, making it suitable for typical automation loads and panel power distribution while maintaining safe operating limits.
Yes. The transformer features a NEMA 3R enclosure designed for indoor-outdoor service and a shielded construction to mitigate EMI. UL Listed certification adds safety assurance for outdoor or semi-exposed installations. To maximize longevity, install away from direct exposure to aggressive chemicals and ensure proper ventilation within the enclosure to manage heat under outdoor operating conditions.
Maintenance is typically minimal beyond periodic inspections of mounting and terminations. Ensure wire terminations stay secure, monitor for signs of overheating, and confirm the unit remains within its rated temperature rise and insulation limits. The UL Listed certification and rugged enclosure support reliable long-term operation, reducing unplanned downtime in automated systems.
The compact, wall-mount design saves cabinet space and reduces installation time in new builds or retrofits. Its 10 kVA capacity supports multi-point loads without oversizing, while the shielded, indoor-outdoor enclosure lowers EMI concerns and weather-related maintenance. With UL Listing and straightforward wiring (240/480 V to 120/240 V), procurement, installation, and long-term reliability translate to lower total cost of ownership.
