Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated EP design with aluminum coils delivers rugged, corrosion-resistant performance in harsh environments, reducing maintenance costs and extending service life for outdoor control cabinets and equipment rooms. The 15 kVA, 240/480 V primary to 120/240 V secondary configuration enables flexible power routing for motor starters, programmable logic controllers, and other automation devices, improving energy efficiency and reducing inventory complexity. Tap changers, specified as 2 at +2.5% FCAN and 2 at -2.5% FCBN, ensure stable output under fluctuating loads, minimizing nuisance tripping in critical systems and supporting precise control in dynamic processes. The indoor-outdoor Weathershield rating and NEMA 4X enclosure simplify installation in mixed environments, enabling quicker commissioning and safer service. A compact footprint combined with a straightforward mounting arrangement enhances site compatibility and reduces installation labor costs, delivering a compelling total cost of ownership advantage for industrial power management and distribution needs.

FAQs
Begin with verifying enclosure compatibility (NEMA 4X) for the site, ensure adequate clearance for tapping and cooling, and use the 2 at +2.5% FCAN 2 at -2.5% FCBN taps to set the voltage balance. Mount the transformer securely to a rated panel base, connect primary and secondary leads per the 240/480 V to 120/240 V configuration, and confirm labeling and protective devices are sized for 15 kVA. Include appropriate isolation and grounding for safe, compliant operation.
The S20D11S15SS4X is a 60 Hz, single-phase transformer offering 15 kVA rated power with primary voltages of 240 V and 480 V and secondary voltages of 120/240 V. The tap settings allow ±2.5% adjustments (2 taps at +2.5% FCAN and 2 taps at -2.5% FCBN) to maintain stable output under varying load and input conditions.
Yes. The transformer features a NEMA 4X enclosure designed for indoor-outdoor use and is specified for environments requiring robust protection against moisture and corrosion. The catalog notes also indicate an indoor-outdoor weathershield, making it suitable for outdoor control panels and exposed electrical rooms within industrial facilities.
