FAQs
The S20N11S10LS47 is designed for general-purpose use with a 179 frame and 197 lb weight, enabling stable mounting in standard electrical cabinets and equipment rooms. It features aluminum winding and a 3A wiring connection, with a NEMA 3R enclosure suitable for indoor-outdoor installations. The transformer accepts 240 V or 480 V primary input and provides 120/240 V secondary outputs, streamlining panel wiring and reducing the need for additional step-down equipment.
This transformer operates at 60 Hz single-phase with a 10 kVA (10,000 VA) rating. Primary voltage options are 240 V and 480 V, while secondary voltage is 120/240 V. These specs support standard control circuits and lighting runs in commercial and light industrial environments, delivering predictable voltage conversion and minimizing regulation issues in demanding panels.
Yes. The S20N11S10LS47 uses an indoor-outdoor rated enclosure (NEMA 3R) and is described as having a weather-resistant Weathershield design. This makes it suitable for outdoor or semi-exposed installations such as exterior equipment rooms, loading docks, and sheltered outdoor panels, enabling flexible deployment without separate weather protection.
The S20N11S10LS47 carries UL Listing, indicating conformance with recognized electrical safety standards. Its NEMA 3R enclosure further supports regulatory and safety expectations for weather-resistant, indoor-outdoor service. For installation teams, this means straightforward approval in most U.S. facilities and compliant operation in mixed-use environments.
With a robust 10 kVA rating, durable aluminum windings, and a weather-resistant enclosure, the transformer minimizes voltage-related faults and reduces downtime on critical loads. The UL Listed safety certification simplifies compliance, while the compact footprint and standard primary-secondary pairing streamline stocking, servicing, and field replacements. Overall, this translates to lower lifecycle costs, faster maintenance, and greater reliability for power distribution in automation environments.
