FAQs
Install the S20N11S01X upright in a commercially rated enclosure rated for NEMA 3R environments. Ensure proper rated clearance for cooling, connect to 240 V or 480 V main with 120/240 V secondary leads, and secure with standard mounting hardware. Maintain proper insulation, follow applicable wiring codes, and verify 50/60 Hz operation for reliable performance.
This transformer is a single-phase unit rated at 1 kVA, with primary voltages of 240 V or 480 V and a secondary of 120/240 V. It operates at 50-60 Hz and features an aluminum coil with a temperature rise of 115 °C. These specs deliver stable control power with efficient heat management, supporting PLCs, relays, and signal conditioning without excessive footprint.
Yes. The S20N11S01X uses an EP encapsulated design inside a NEMA 3R enclosure, specified for indoor-outdoor use. Its aluminum winding and 1 kVA rating provide robust performance in harsh environments, making it well-suited for factory floors, outdoors near equipment, and general automation installations that require reliable isolation.
The transformer is UL Listed, which confirms conformity with widely recognized electrical safety standards. This certification simplifies vendor qualification, supports compliance in regulated facilities, and reduces procurement risk for projects requiring proven safety in industrial environments.
Eaton offers a 1-year warranty from installation or 18 months from shipment, whichever comes first. Routine maintenance focuses on visual inspections of connections and enclosure integrity. The robust aluminum coil and encapsulated design minimize corrosion and heat-related degradation, contributing to lower maintenance costs and improved total cost of ownership.
