Encapsulated copper-wound design delivers high reliability in confined spaces and reduces acoustic output, improving overall system uptime and reducing service calls. Feature → Business Impact → Application: Copper coil windings provide low resistance and high efficiency, cutting energy losses in motor control centers and distribution panels. Application: general-purpose control transformers in industrial plants; the efficiency translates to lower operating costs and cooler operation. The NEMA 3R enclosure enables indoor-outdoor installation, simplifying multi-site deployments and reducing enclosure inventory. Application: outdoor substations and weather-exposed control rooms; benefit: fewer weather-related failures and faster commissioning. The 2 at +2.5% FCAN and 2 at -2.5% FCBN taps offer voltage tuning to keep load voltages within tolerance, improving equipment performance and reducing nuisance tripping. Application: sites with fluctuating input voltages; impact: stabilized downstream devices. With 60 Hz single-phase operation and 440 V primary to 110/220 V secondary, compatibility with common plant power architectures is straightforward, accelerating installation timelines. Application: industrial machinery and automation panels; measurable outcomes: improved voltage accuracy, reduced downtime, and easier maintenance planning. Engineered for 115 °C rise and a 37.5 kVA rating, it accommodates continuous operation under demanding loads, supporting apps like conveyors, pumps, and control logic supplies. Application: mission-critical process lines; value: higher reliability and longer service intervals. The indoor-outdoor versatility and CSA/UL certs simplify procurement and compliance, while the copper construction supports long-term performance in harsh environments. Application: plant-wide transformers that must meet strict electrical standards, with reduced total cost of ownership.

FAQs

The S44D14S37CU is a single-phase transformer with a 440 V primary and 110/220 V secondary. It includes taps at +2.5% FCAN and -2.5% FCBN to tune voltage in sites with fluctuating input. Verify your service provides 440 V line-to-line and that your downstream equipment is rated for 110/220 V. For multi-voltage requirements, consider pairing with appropriate protective devices and wiring per NEC guidelines.
This Eaton unit is CSA Certified and UL Listed, and uses a NEMA 3R enclosure suitable for indoor-outdoor use. These certifications and enclosure ratings help meet industry safety and reliability standards, enabling outdoor installations without extra protective housings and simplifying supplier qualification for regulated facilities.
Install the transformer in a dry, ventilated space or protected outdoor location to leverage the NEMA 3R enclosure. Use copper windings for high reliability and low resistance losses, and ensure proper mounting to support the 872 lb weight. Plan for 60 Hz operation and provide appropriate protective relays and fusing to handle 37.5 kVA loads.
Yes. The indoor-outdoor Weathershield capability and NEMA 3R enclosure are designed for outdoor control panels and exposed installations. The 37.5 kVA rating supports moderate-to-heavy loads, while the voltage taps enable voltage regulation for varying input conditions and motor control loads, reducing nuisance tripping and wear.
Eaton’s warranty policy provides one year from installation or eighteen months from shipment, whichever occurs first. This short-circuit protection friendly policy complements CSA/UL certifications, giving you confidence in service life and maintenance planning for mission-critical applications.
