FAQs
For safe and compliant installation, ensure adequate enclosure clearance and proper mounting within the NEMA 4X rated housing. Verify panel labeling matches the 240/480 V primary and 120/240 V secondary outputs, and provide proper ventilation to manage the 80 °C rise rating. Use appropriate electrical connections and strain relief to minimize vibration and wear over time.
Key specs include a 10 kVA volt-ampere rating, 60 Hz frequency, single-phase operation, primary voltages of 240 V and 480 V, secondary voltages of 120/240 V, an 80 °C temperature rise, and a copper winding construction designed for efficiency and reliability in industrial environments.
Yes. The 10 kVA rating and 120/240 V secondary output are well-suited for powering control panels and automation hardware. Its copper windings offer improved efficiency, while the NEMA 4X enclosure supports indoor-outdoor installation, simplifying integration with existing panel designs and reducing heat-related issues in automation setups.
Manufacturer-specific certifications may vary by region. The unit features a NEMA 4X enclosure for weather protection and rugged construction suitable for indoor-outdoor use. For brand-specific listings (UL/CE, etc.), verify with Eaton or your regional distributor to ensure compliance for your facility.
The transformer’s copper windings and no-tap design reduce energy losses and maintenance needs, lowering operating costs and service interruptions.
