FAQs
Install the S27N11S76SS by mounting it inside a NEMA 3R enclosure sized for the 5.75 in by 5.99 in footprint and 11.28 in height. Ensure proper ventilation and clearance, then wire the 277 V primary to the 524A connection and connect loads to the 120/240 V secondary. Follow UL Listed guidelines and secure with Grade 304 hardware.
With a NEMA 3R enclosure and an indoor-outdoor rating, the S27N11S76SS is built to withstand weather, moisture, and dust without compromising electrical performance. The aluminum coil design and compact footprint help fit tight spaces in outdoor panels, while UL Listing supports compliance and reduces design risk during audits.
Key specs include a 0.75 kVA rating, 277 V primary, 120/240 V secondary, single-phase operation at 60 Hz, and a 115 °C rise. These values translate to reliable feeder power for small loads in industrial control panels and lighting circuits, with predictable voltage regulation and fast response to load changes.
UL Listed certification confirms safety compliance and inspection readiness, while the NEMA 3R enclosure rating provides protection against rain, snow, and contaminants. This combination reduces risk during audits and supports installation in mixed indoor-outdoor environments.
Compact size and aluminum winding contribute to a lighter, easier-to-install unit that reduces panel space and installation time. The rugged enclosure and weather rating minimize maintenance, while the included warranty (one year from install or 18 months from shipment) lowers lifecycle risk and supports longer uptime.
