FAQs
Installers should plan for a secure, level mounting surface with proper clearance for heat dissipation and access to connections. The unit utilizes a NEMA 3R enclosure suited for indoor-outdoor environments and weighs lightly thanks to an aluminum coil design. Ensure compatibility with 240/480 V primary and 120/240 V secondary loads, and observe the 60 Hz input frequency for correct operation.
The device is a single-phase 3 kVA transformer designed for 60 Hz operation. Primary voltages supported are 240 V and 480 V, with a secondary output of 120/240 V. The aluminum coil construction supports efficient heat dissipation, and the unit is UL Listed for safety and reliability in control panels and automation gear.
Yes. The enclosure is rated NEMA 3R with indoor-outdoor suitability, and catalog notes indicate corrosion-resistant options such as Grade 304 stainless steel with NEMA 4X rating. This makes the S20N11S03SS4X appropriate for outdoor or semi-exposed installations where moisture, dust, or washdown are considerations.
The transformer is UL Listed, providing recognized safety certification that helps with compliance, supplier qualification, and regulatory audits. While CE/IP specifics aren’t listed in the provided data, the UL certification, NEMA 3R enclosure, and indoor-outdoor rating collectively support compliance in many industrial environments and streamline procurement for regulated facilities.
With a rugged encapsulated design, corrosion-resistant enclosure options, and a 3 kVA rating, the unit minimizes unexpected downtime and reduces maintenance intensity. A one-year Eaton warranty (or 18 months from shipment) adds financial protection, while UL certification and robust construction lower lifecycle costs by extending service intervals in demanding automation applications.
