FAQs
Plan for a sturdy mounting surface to support a 144 lb unit, and ensure adequate clearance for ventilation and service access. The transformer uses a compact footprint (9.89 in L x 10.38 in W x 16 in H) with a NEMA 3R enclosure suitable for indoor-outdoor locations. Mounting should align with 240/480 V primary and 120/240 V secondary wiring and follow local electrical codes.
The S20N11E07CUSS provides 7.5 kVA at 60 Hz, single-phase, with a primary of 240 V or 480 V and a secondary of 120/240 V. It uses copper windings and has an 115 °C temperature rise rating. The enclosure supports indoor-outdoor use, and the unit carries UL Listed certification for safety and compliance in industrial power distribution applications.
Yes. The NEMA 3R enclosure and indoor-outdoor capability (Weathershield) make it appropriate for outdoor or wash-down environments. Its Grade 304 stainless steel enclosure adds corrosion resistance, while the copper windings and encapsulated design help protect against moisture ingress and EMI, ensuring reliable operation in exposed locations.
The S20N11E07CUSS is UL Listed, which confirms compliance with recognized safety standards. The enclosure is designed for indoor-outdoor use (NEMA 3R), and the stainless steel housing provides corrosion resistance in challenging environments. The product also features electrostatic shielding to reduce EMI coupling in demanding electrical installations.
