Feature → Business Impact → Application: The encapsulated construction housed in a 304SS enclosure protects critical windings and components from dust, moisture, and corrosion, which translates to lower maintenance costs and increased uptime in harsh environments such as outdoor electrical rooms and damp factory floors. This enables engineers to confidently deploy the transformer in outdoor or semi-exposed panels, reducing enclosure fan or heater needs while maintaining reliability. Feature → Business Impact → Application: NEMA 3R enclosure and Frame 175 provide rugged housing that withstands washdown and incidental water exposure, improving compliance with environmental standards and simplifying installation in outdoor or semi-outdoor facilities. This structure supports quick panel integration in machine builds and distributed control cabinets, streamlining procurement and on-site work. Feature → Business Impact → Application: 208 V primary with 120/240 V secondary enables common utility voltages to power control circuits and signaling devices, reducing wiring complexity and field conversions. It supports compact panel design and faster commissioning in machinery and process control, especially where space is constrained. Feature → Business Impact → Application: No taps means a fixed voltage ratio, enhancing reliability and reducing field-configured risks. The predictable output simplifies downstream design, drives consistent performance, and lowers commissioning time for standardized control loops across manufacturing lines. Feature → Business Impact → Application: 60 Hz single-phase operation aligns with typical facility power, encouraging seamless integration into standard electrical distributions and control schemes, which minimizes compatibility checks and accelerates project timelines. Feature → Business Impact → Application: 65 lb weight and robust mounting considerations encourage the use of proper hardware and safety planning, reducing installation injuries and ensuring secure, vibration-resistant operation in industrial environments. This translates to fewer mid-project delays and longer transformer life in dynamic production settings.

FAQs
Plan for the unit's weight and secure mounting using appropriate hardware to support the 65 lb transformer within a 304SS NEMA 3R enclosure. Ensure adequate clearance for heat dissipation and wiring access, follow UL/CSA guidelines, and note that the device uses a fixed 208 V primary with 120/240 V secondary (no taps). If other voltages are required, select a different model.
Key specs include 60 Hz frequency, single-phase operation, 208 V primary, and 120/240 V secondary. The enclosure is NEMA 3R with a Frame 175, Type EP. Temperature rise is 115 °C, and the volt-ampere rating is listed as 3. This data supports low-power control or signaling applications and should be cross-checked with the datasheet for exact VA requirements.
Yes. The transformer is designed for rugged use in outdoor or semi-exposed conditions thanks to the NEMA 3R enclosure and 304SS enclosure notes. It should be more than suitable for outdoor control panels and damp indoor environments, provided ambient conditions stay within typical operating specs and proper mounting/ventilation are maintained.
This Eaton transformer is CSA Certified and UL Listed, confirming compliance with recognized safety and performance standards. These certifications help satisfy regulatory requirements for electrical equipment in many facilities and projects, support traceability, and reduce risk during audits and inspections.
The listed warranty is Eaton’s standard policy: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on the encapsulated design to minimize moisture ingress and corrosion. Routine inspections, secure mounting, and verifying insulation integrity help maximize service life and minimize unexpected downtime.
