Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated EP construction protects windings from moisture, dust, and mechanical impact. This increases reliability and lowers maintenance costs in harsh industrial settings. Use this in control panels that face outdoor exposure or damp environments. The 1 kVA rating with a 277 V primary and 120/240 V secondary delivers scalable power for automation equipment, PLC inputs, and lighting, while supporting 60 Hz operation typical of North American industrial systems. The NEMA 3R enclosure and Weathershield designation enable true indoor-outdoor installation, reducing the need for additional enclosure protection and simplifying site permitting. Aluminum coil construction provides a lighter yet durable winding, improving transportability and reducing installation stress. Wiring connections (2B) and a 2-tap option at -5% FCBN offer flexibility during commissioning, minimizing voltage drop on long runs. The compact footprint and 26 lb weight help with fitment in tight panels and retrofit projects, lowering total cost of ownership. Warranty terms and UL safety certification reinforce compliance and long-term support for high-demand automation environments.

FAQs
This transformer uses a compact 5.75 in depth, 5.99 in width, and 11.28 in height with a 26 lb weight, making it suitable for tight panel spaces. It features a 2B wiring connection and a 2-tap -5% FCBN option to accommodate voltage tolerance and wiring layouts. For outdoor or damp environments, rely on the NEMA 3R enclosure and indoor-outdoor capability to minimize additional protective measures.
The unit is a 1 kVA, single-phase transformer with a 277 V primary and 120/240 V secondary. It operates at 60 Hz and has a temperature rise of 115 °C. This config supports powering PLCs, relays, controls, and lighting in standard industrial automation setups while maintaining voltage stability.
Yes. The transformer features a NEMA 3R enclosure and Weathershield designation for indoor-outdoor use, providing moisture and dust resistance. This makes it appropriate for outdoor panels or semi-protected spaces, reducing the need for additional protective enclosures and simplifying installation in variable environments.
The S27G11S01A carries UL Listed safety certification, signaling conformity with recognized safety standards for electrical equipment. For many industrial projects, UL Listing assists with regulatory compliance and customer acceptance, reducing vendor risk and expediting procurement in control-panel assemblies.
With a 1 kVA rating, rugged enclosure, and simplified installation (2B wiring, 2-tap options), you reduce spare-part inventory and commissioning time. The aluminum coil design lowers weight and handling costs, while UL listing and a durable indoor-outdoor rating minimize maintenance and downtime, delivering measurable cost savings over a typical control-panel lifecycle.
