FAQs
Plan for appropriate mounting clearance, accessible lead connections, and proper isolation from vibration. The unit uses a 480 V primary and 120/240 V secondary in a single-phase configuration, housed in a NEMA 4X enclosure suitable for indoor-outdoor use. Ensure compatible panel spaces and secure mounting to a solid base, with proper grounding and clear labeling to meet plant safety standards.
Yes. The transformer features a NEMA 4X enclosure with Grade 304 stainless steel construction, designed for indoor-outdoor service and resistance to corrosion in wash-downs and harsh environments. While it’s robust, verify ambient conditions and provide appropriate protection from direct, extreme exposure if needed, following Eaton installation guidelines.
Voltage regulation is provided via taps: two at +2.5% (FCAN) and four at -2.5% (FCBN). This allows fine-tuning of the secondary voltage under load to maintain PLC and drive stability. Installers should follow the manufacturer’s wiring diagram, ensure secure tap connections, and perform voltage measurements with loaded equipment to confirm target voltages within tolerance.
Certifications are listed as Contact Manufacturer. The unit complies with practical standards for power distribution devices, including a 60 Hz single-phase design, copper windings, and a NEMA 4X enclosure suitable for indoor-outdoor use. For formal certification documentation (CE, SIL, etc.), consult Eaton to confirm the exact approvals for your region and application.
The S48M11S50CUSS4X uses copper windings and a robust encapsulated design to reduce losses and leakage, delivering reliable uptime and predictable performance. With a 50 kVA rating, it supports critical control circuits and automation panels, lowering field wiring changes. The unit’s durable enclosure lowers maintenance needs in harsh environments, contributing to favorable total cost of ownership over its service life.
