FAQs
Begin by verifying the panel rating and ensuring space for the NEMA 4X enclosure. Mount the transformer in a standard, non‑combustible panel area with proper clearance for heat dissipation. Connect the 480 V primary to the incoming power and the 120/240 V secondary to the control circuitry. Use strain‑relief and appropriate wire gauges, and confirm grounding per EMC/panel standards. The encapsulated design supports rugged environments, reducing the need for frequent resealing or moisture protection.
Key specs include a 3 kVA power rating, 1‑phase operation, 480 V input, 120/240 V output, and an 115°C rise rating. The NEMA 4X enclosure provides environmental protection, enabling reliable operation in challenging conditions. For applications like sensors, relays, and MCCs, these figures translate to predictable voltage delivery, steady load handling, and minimal derating in typical factory temps.
Yes. The encapsulated design with a NEMA 4X enclosure is specifically geared toward harsh industrial environments, offering dust, moisture, and corrosion resistance. Its 3 kVA, 1‑phase configuration fits common automation loads, making it suitable for control panels, machine tools, and PLC‑driven equipment where reliable power is essential and downtime must be minimized.
Certifications can vary by region and variant. The data indicates certification details should be confirmed with the manufacturer. In practice, Eaton transformers in this class commonly offer CE and UL/CSA options depending on the market. Always verify current certification status with Eaton to ensure regulatory alignment for your specific installation.
Encapsulation protects windings and cores from moisture, dust, and vibration, reducing corrosion and mechanical wear. This leads to lower maintenance frequency, longer service life, and reduced downtime costs. In return, your automation projects see improved uptime, steadier power delivery to critical loads, and a lower total cost of ownership over the transformer’s lifetime.
