Ventilated dry-type design enables superior heat management, improving reliability and reducing derating in hot industrial environments. Business impact: fewer outages, longer component life, and lower cooling energy costs in panels and machine centers. Application: ideal for general distribution in control rooms and equipment rooms where airflow and ventilation are leveraged for cooling. Aluminum windings reduce weight and corrosion risk while maintaining strength, enabling easier installation and service on congested layouts. Application: supports retrofits and new builds with constrained space. The multi-tap primary (1 at +5% FCAN, 2 at -5% FCBN, plus 2 at +2.5% FCAN and 4 at -2.5% FCBN) provides flexibility to accommodate voltage fluctuations on site, reducing the need for additional regulation equipment. Impact: minimizes voltage derating and improves uptime. Application: critical in facilities with variable supply conditions or long feeder runs. 15 kVA, single-phase, 240/480 V primary to 120/240 V secondary with 60 Hz operation aligns with standard plant distributions, enabling straightforward integration into existing equipment. Frame CS15C102 ensures a compact, compatible footprint for panel builders and rack installations. Temperature rise rated at 150°C supports reliable operation in moderately warm environments, avoiding excessive cooling or derating. Warranty terms (one year from installation or eighteen months from shipment) reduce risk for procurement and maintenance planning. In practice, these features support measurable gains in efficiency, compliance, and total cost of ownership for industrial power distribution.

FAQs
The T20P11S15ZZ is a 15 kVA, single-phase device with a CS15C102 frame. Plan for adequate ventilation around the unit to support its open-core, ventilated design. Allow sufficient clearance in front for service access, and ensure mounting supports are rated for approximately 142 lb. Use standard panel mounting practices and maintain clearance per your enclosure specifications to optimize heat dissipation.
Key specs: 15 kVA, single-phase, 60 Hz, primary 240/480 V, secondary 120/240 V. Tap configuration includes 1 at +5% FCAN, 2 at -5% FCBN, 2 at +2.5% FCAN, and 4 at -2.5% FCBN. These taps help accommodate supply variance and maintain output within tolerance, reducing the need for external regulation in many installations.
Yes. This transformer is a general-purpose, dry-type, ventilated solution designed for distribution in control panels, machine centers, and equipment rooms. The DS-3 design and aluminum windings support reliable operation in typical industrial environments, while the 15 kVA rating provides ample headroom for control circuits and auxiliary loads without frequent derating.
The unit carries UL Recognized certification, underscoring safety, reliability, and regulatory compliance for electrical distribution components. UL recognition helps streamline procurement and installation in many industrial facilities, supplier audits, and safety inspections, reducing qualification time for new builds or upgrades and aligning with common American electrical standards.
Warranty is Eaton Selling Policy 25-000, offering one year from the date of installation or eighteen months from shipment, whichever occurs first. This provides a defined window for performance validation and service planning. For maintenance, schedule periodic insulation and winding checks, monitor temperature rise within spec, and ensure ventilation remains unobstructed to sustain reliability.
