FAQs
For installation, plan a secure, grounded mounting within an IP-rated space and allow for proper clearance for heat dissipation. Use the NEMA 4X enclosure for outdoor or damp environments, and verify voltage compatibility across the 190–440 V primary and secondary ranges. Ensure proper wire sizing and secure terminations to minimize heat buildup and faults.
This model provides a 25 kVA VA rating at 50-60 Hz, single-phase operation, with primary and secondary voltage options from 190 V to 440 V. The aluminum coil supports efficient thermal performance, and the 150 °C rise specification guides thermal margins during peak loads, helping prevent overheating in typical automation scenarios.
Yes. The transformer is designed with a NEMA 4X enclosure and an indoor-outdoor weathershield, offering weatherproof and corrosion-resistant protection. In environments with humidity, dust, or washdown requirements, this enclosure type helps maintain reliability and reduces maintenance intervals.
The unit features a NEMA 4X-rated enclosure and a corrosion-resistant construction suitable for harsh environments. Certification details beyond these enclosure characteristics are provided by Eaton; consult the manufacturer for any additional certifications such as CE, SIL, or IP ratings relevant to your region and application.
