Feature: Open core-coil ventilated design enables superior airflow and heat dissipation. Business Impact: Lower temperature rise and improved efficiency reduce cooling requirements and extend service life. Application: Ideal for compact control panels and dry-type installations in harsh industrial environments. Feature: 240 x 480 V primary and 120/240 V secondary configuration provides flexible voltage conversion. Business Impact: Simplifies wiring and reduces the need for multiple transformers in mixed-voltage systems. Application: Suitable for machine control, automation panels, and process equipment. Feature: 75 kVA rating supports medium-load power distribution with headroom for startup surges. Business Impact: Improves system reliability and reduces the risk of voltage dips during peak demand. Application: Industrial automation and process lines requiring steady power. Feature: Tap settings (+5%/2×-5% and ±2.5%/4×-2.5%) offer voltage regulation to maintain stable output under varying input conditions. Business Impact: Enhances performance across fluctuating supply networks, minimizing equipment stress. Application: Critical for sensitive controls and PLCs in variable-power environments. Feature: 1-phase, dry-type configuration with robust construction and ventilation. Business Impact: Lower maintenance needs, easier installation, and safer operation in clean-room-adjacent or dusty plants. Application: Control panels, distribution centers, and machine-automation rooms. Industry insight: This transformer aligns with typical industrial power-management practices, helping facilities meet efficiency targets while simplifying procurement through a single, versatile unit that reduces parts variation and end-to-end installation time.

FAQs

Install the transformer on a ventilated mounting rack inside a dedicated control panel or enclosure, ensuring adequate clearance for cooling. Connect the 240/480 V primary to the supply and the 120/240 V secondary to the loads, using the offered voltage taps to fine-tune output. Verify grounding and follow manufacturer wiring diagrams to avoid phase or tap misconfigurations.
Key specs include 75 kVA VA rating, 240 x 480 V primary, 120/240 V secondary, and 1-phase operation. Taps offer +5% and -5% (with ±2.5% and ±4 × -2.5%) to adjust secondary voltage. The transformer is designed for a 150°C rise with ventilated open-core construction to support reliable operation in challenging environments.
Yes. The T20P11S7516ZZ is built for dry-type, 1-phase distribution in industrial panels, providing compact footprint, robust cooling, and adjustable taps. Its 75 kVA rating supports typical mid-load plant sections, machine controls, and automation lines while maintaining voltage stability under load variations.
Certification details vary by region and application. The datasheet notes certifications as 'Contact Manufacturer,' so confirm specific CE, UL, SIL, or IP ratings with Eaton or your local distributor to meet local safety and performance requirements before purchase or installation.
The ventilated open-core design enhances cooling, reducing thermal stress and extending service life with lower maintenance needs. Its dry-type construction minimizes oil-related risks, and the unit’s modularity simplifies installation and future upgrades, contributing to lower total cost of ownership and faster return on investment.
