FAQs
Choose a location with adequate clearance for its 6.52 in depth, 13.41 in height, and 6.37 in width footprint. Mount within a NEMA 3R-rated enclosure for indoor-outdoor service, and plan for 240/480 V primary input and 120/240 V secondary output. The 41 lb weight and 90A wiring connection support robust, space-efficient panel layouts. Ensure UL Listed compliance and verify wiring practices meet local electrical codes.
The S20N11E02A provides 2 kVA at 60 Hz in a single-phase configuration with primary voltages of 240 V or 480 V and secondary 120/240 V. Its 115 °C rise rating ensures safe, reliable operation under typical industrial heat loads. Aluminum coil construction and encapsulated EP design minimize noise and thermal stress, supporting consistent performance in demanding environments.
Yes. The transformer uses a NEMA 3R enclosure and is rated for indoor-outdoor service, making it well-suited for exposed or semi-protected installations. Its electrostatically shielded construction and 60 Hz single-phase design support control panels, automation equipment, and motor control centers, while UL Listed certification provides regulatory assurance for integration into regulated systems.
The S20N11E02A is UL Listed, indicating compliance with recognized safety standards. It features a NEMA 3R enclosure suitable for indoor-outdoor use and is designed for 60 Hz, single-phase operation with a 2 kVA rating. The 115 °C rise and electrostatically shielded construction contribute to reliable performance in industrial settings.
Plan for routine visual inspections and periodic electrical checks per your maintenance program. The one-year warranty (or eighteen months from shipment) provides initial protection, while the robust epoxy encapsulation and aluminum windings reduce corrosion and wear. The compact footprint and reduced wiring complexity lower installation time and panel cost, contributing to a favorable total cost of ownership over the device’s life cycle.
