FAQs
For installation, verify the panel enclosure provides adequate clearance for the encapsulated transformer and accessible mounting points. Confirm the 1-phase input wiring matches 240/480 V and route the 120/240 V secondary conductors to the controlled loads with proper isolation. Use appropriate fusing and overcurrent protection per local codes, and reference the Eaton datasheet and catalog for recommended mounting orientations and torque specifications.
The S20N11P01B is a single-phase transformer rated at 1 kVA. It provides a primary input of 240/480 V and a secondary output of 120/240 V. These ratings support common control circuits in industrial applications, enabling efficient voltage conversion within compact enclosures.
Yes, the S20N11P01B is designed for 480 V inputs to 120/240 V outputs in single-phase configurations, making it suitable for control panels and equipment that require lower voltage levels for relays, controllers, and sensors while maintaining isolation and protection in harsh environments.
Certifications for this product are listed as available upon request from the manufacturer. To ensure compliance with your facility’s regulatory requirements, contact Eaton for CE, SIL, IP, or other approvals and obtain the official documentation before procurement or installation.
