FAQs
Key considerations include its 230 lb weight, dimensions (13.38 in W x 10.52 in D x 19 in H), and the 524S wiring connection. The NEMA 3R outdoor-rated enclosure supports indoor-outdoor service, while its single-phase 400 V to 120/240 V outputs fit standard panel boards. Plan for adequate clearance and mounting access for servicing.
Crucial specs are 7.5 kVA VA rating, 400 V primary, 120/240 V secondary, 50-60 Hz frequency, copper windings, and a 115 °C rise. The unit is UL Listed and designed for single-phase operation in industrial environments, ensuring reliable voltage transformation with built-in safety and compliance.
Yes. The S39N11S07XCU uses a NEMA 3R enclosure with indoor-outdoor capability and Weathershield, making it suitable for outdoor machinery, outdoor panels, and damp environments. Its 7.5 kVA rating supports a range of control and distribution loads in industrial automation setups.
The transformer is UL Listed, indicating compliance with recognized safety standards. Its NEMA 3R enclosure provides protection for outdoor service, while catalog notes confirm 50/60 Hz compatibility. This combination supports code compliance in many industrial facilities and reduces vendor risk during audits.
With copper windings and robust encapsulation, maintenance needs are typically low and predictable. The included 1-year warranty (or 18 months from shipment) minimizes risk, while UL listing and durable enclosure reduce downtime and replacement costs during plant operation, contributing to a favorable total cost of ownership.
