FAQs
The T20P11F15CUESNV is a DS-3 dry-type transformer with a compact footprint and a frame 817N. For installation, ensure indoor, dry location with accessible service clearances per Eaton guidance, platform or panel mounting compatibility, and appropriate lifting provisions for the 383 lb weight. Check the product dimensions: 19.5 in depth, 37.53 in height, and 22.59 in width to confirm enclosure integration and panel cutouts.
Key specs include a 15 kVA rating with primary voltages of 240/480 V and secondary voltages of 120/240 V, designed for 60 Hz operation. Copper windings and an electrostatic shield support efficiency and EMI protection. Tap settings include 1 at +5% FCAN, 2 at −5% FCBN × 2, and 4 at −2.5% FCBN, enabling voltage regulation for fluctuating inputs.
Yes. Its totally enclosed non-ventilated enclosure minimizes dust ingress and moisture exposure, while the DS-3 design provides rugged service in factory settings. The unit supports reliable power to automation controllers and drives, with low maintenance needs due to dry-type construction and copper windings, making it well-suited for panelboards and machine control applications.
Certification details for the T20P11F15CUESNV are provided by the manufacturer. The product page notes Certifications: Contact Manufacturer, so engage Eaton to obtain the exact safety and regulatory credentials (regional compliance, UL/CE equivalents, and any industry-specific approvals) to meet your facility’s compliance requirements.
Warranty is Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. The dry-type design reduces ventilation-related maintenance, and copper windings plus shielding contribute to long-term reliability and lower life-cycle costs. For ROI, consider predictable uptime, reduced cooling energy, and minimized panel-space constraints in new builds or retrofits.
