FAQs
Installers should account for the 41 lb weight and the 68P4X frame when mounting the transformer inside a panel. The NEMA 4X enclosure supports indoor-outdoor usage, reducing corrosion risk in harsh environments. Plan wiring to match the 240/480 V primary and 120/240 V secondary configuration and provide adequate clearance for cooling.
This unit is a single-phase transformer rated at 2 kVA. It supports primary voltages of 240 V and 480 V, with secondary voltages of 120/240 V. It operates at 60 Hz and uses copper windings to deliver efficient power transfer with a 115 °C rise, suitable for typical industrial control loads.
Yes. The enclosure is rated NEMA 4X with a code‑friendly 304 stainless steel construction, providing robust protection in indoor-outdoor settings. This makes it appropriate for environments that require corrosion resistance and washdown capability while maintaining reliable control power.
The product data lists Certifications as 'Contact Manufacturer,' so regulatory approvals should be confirmed with Eaton. In practice, transformers in this class commonly require CE marking and UL/CSA approvals depending on region; verify the exact certifications for your installation with the supplier before procurement.
Encapsulated copper windings and a sealed NEMA 4X enclosure minimize moisture ingress and contaminants, reducing maintenance needs and downtime. The 2 kVA rating provides adequate headroom for control circuits, while the 1‑year warranty offers support for field reliability, contributing to lower lifecycle costs in automation applications.
