FAQs

When installing the S23N15S07XCU, ensure it is mounted within its NEMA 3R-rated enclosure and that the 511AV wiring harness matches the panel’s terminations. Verify clearance for air flow and heat dissipation, and use appropriate connectors to maintain enclosure integrity and electrical safety.
The unit is a single-phase transformer rated at 7.5 kVA with a 50-60 Hz frequency rating, copper windings, and a 115 °C rise. These specs provide reliable voltage transformation (230 V to 115 V) with consistent regulation and heat tolerance under typical factory loads.
Yes. The transformer is designed for indoor-outdoor use with a NEMA 3R enclosure. It carries CSA Certified and UL Listed certifications, delivering recognized safety compliance for a wide range of industrial settings.
Eaton provides a standard warranty policy (Selling Policy 25-000) of one year from installation or eighteen months from shipment, whichever occurs first, along with access to Eaton’s technical support and product documentation for ongoing reliability.
Copper windings offer lower resistance losses and superior thermal performance, improving efficiency and heat dissipation. This translates to more stable voltage regulation, longer service life, and reduced maintenance despite frequent on/off cycling common in automation panels.
