Feature: Totally enclosed non-ventilated design (DS-3) protects windings from dust and contaminants, enabling reliable operation in open panels and harsh factory environments. Business Impact: Reduces cooling demands, minimizes maintenance, and extends service intervals, translating to lower total cost of ownership. Application: Ideal for control cabinets, machine lines, and industrial automation zones where environment ruggedness matters. Feature: 15 kVA single-phase rating with dual primary 240/480 V and secondary 120/240 V. Business Impact: Offers flexible distribution from common utility feeds, reducing spare parts and stock-keeping costs while speeding panel design and commissioning. Application: Suitable for power distribution in manufacturing cells, process lines, and machine tools that require reliable step-down conversions. Feature: Tap changes with 1 at +5% FCAN, 2 at -5% FCBN, and 2 at +2.5% FCAN, plus 4 at -2.5% FCBN. Business Impact: Enables precise voltage regulation to compensate for input swings without overloading downstream equipment, reducing overheating and flicker. Application: Critical in areas with variable feeder voltages, remote sites, and data centers with unstable power quality. Feature: Aluminum windings provide corrosion resistance and cost-efficiency, with lighter handling during installation and simplified field service. Business Impact: Reduces total cost of ownership through lower material costs and easier maintenance, while maintaining robust electrical performance. Application: Suitable for environments where moisture, humidity, or airborne contaminants are a consideration, including manufacturing floors and packaging lines. Feature: General specifications and warranty coverage validate long-term reliability, with a frame 817N, a weight around 340 lb, and a one-year warranty from installation or eighteen months from shipment. Business Impact: Provides procurement confidence and service support for capital projects, ensuring predictable maintenance budgeting and downtime. Application: Factory takeovers, upgrade projects, and new line installations where dependable transformers are essential. Feature: Documentation and regional certifications available on request. Business Impact: Streamlines approvals and inspection readiness, reducing project risk and speeding commissioning. Application: Organizations pursuing CE, UL, or CSA compliance or customer-specific safety standards will find prepared technical sheets and cross-reference material readily accessible.

FAQs
Install the T20P11F15NV in a well-ventilated, accessible panel area with support for its 19.5 in length and 22.59 in width footprint. Provide adequate clearance for taps and lead connections, and follow wiring diagrams that show 240/480 V primary and 120/240 V secondary wiring. Use proper lugs and torque specs and secure the unit to a rigid base to minimize vibration.
Voltage regulation is enhanced by tapping options that include 1 at +5%, 2 at -5% FCBN, and 2 at +2.5% FCAN, plus 4 at -2.5% FCBN. This allows precise compensation for input swings without overloading downstream equipment, reducing overheating and flicker. During commissioning, align taps and verify stability under expected load profiles.
Certifications for the T20P11F15NV vary by region, and Eaton can supply CE, UL, CSA, or other approvals on request. Check with your procurement team or Eaton technicians to confirm exact documentation for your installation site. If your project requires SIL or IP ratings, specify the environment and compliance requirements early in the specification process.
Warranty coverage for this transformer is one year from installation or eighteen months from shipment, whichever comes first. This policy is complemented by Eaton's after-sales support, spare parts availability, and field service options. When budgeting, factor in calibration and inspection cycles, plus accessibility for periodic thermal checks to maximize uptime and maintain voltage accuracy.
Typical applications include control panels, machine tool feeders, and industrial power distribution in manufacturing facilities, packaging lines, and process plants. The 15 kVA rating and 240/480 V primary enable integration with common facility supplies, while the 120/240 V secondary suits 24 V control circuits. This transformer also supports retrofit projects seeking reliable voltage conditioning.
