FAQs
Install the S20N08P16P using a suitable NEMA 3R enclosure with mounting provisions compatible with the 67P frame. Connect the 240/480 V primary leads using 3D wiring per the Eaton wiring diagram, and terminate the 24/48 V secondary to the control circuit or low-voltage devices. Ensure proper clearance and secure strain relief to maintain UL compliance and safe operation.
Key specs include 60 Hz frequency, single-phase configuration, primary voltage options of 240 V or 480 V, secondary voltage of 24/48 V, and a volt-ampere rating of 1.5 kVA. The unit features aluminum coil material, a 115 °C rise, and is designed for indoor-outdoor service within a NEMA 3R enclosure.
Yes. With its 1.5 kVA rating and dual primary voltages, the S20N08P16P fits standard control panels and machine tool cabinets, providing stable low-voltage supplies for relays, PLCs, and sensors. Its encapsulated design and rugged enclosure help maintain reliability in demanding industrial environments and support compact, compliant panel layouts.
The transformer is UL Listed, supporting essential safety compliance for industrial installations. It uses a NEMA 3R enclosure design, enabling indoor-outdoor use and protection against weather exposure, meaning it can be deployed in exposed panel setups without sacrificing safety.
Encapsulated construction and aluminum windings reduce corrosion risk and improve heat dissipation, contributing to lower maintenance needs and longer service life. The UL Listed certification and rugged NEMA 3R design help minimize field failures, delivering predictable total cost of ownership and faster project payback in automation upgrades.
