Feature → Business Impact → Application: General-purpose encapsulated design provides robust insulation and moisture resistance, reducing field failures and service calls in dynamic environments. This translates to higher uptime for machine controls and panel assemblies in manufacturing lines. Application: Control cabinets in food & beverage, packaging, and material handling where frequent washdowns occur. Feature → Aluminum windings reduce weight and improve heat dissipation, enabling easier mounting and faster installation while preserving efficiency. Application: Portable or rack-mounted transformer solutions in compact spaces where service accessibility matters. Feature → NEMA 4X enclosure with 304 stainless steel construction offers superior protection against dust, water, and corrosion, supporting outdoor or washdown environments. Business Impact → Lower total cost of ownership through longer intervals between maintenance and reduced enclosure refurbishment. Application → Outdoor electrical rooms and outdoor panel boards in harsh climates. Feature → 0.15 kVA, single-phase, 60 Hz, primary 240/480 V and secondary 120/240 V delivers targeted voltage conversion for small control circuits, sensors, and motor control centers. Business Impact → Efficient power conditioning for PLCs, relays, and instrumentation with minimal dissipation and wiring complexity. Application → Machine control panels and distributed I/O stations. Feature → Temperature rise rating of 115 °C ensures reliable performance within typical panel heat budgets, enabling predictable operation under load. Business Impact → Improved thermal management planning and safer installations. Application → High-density control cabinets where thermal margins are tight. Feature → Weathershield Indoor-Outdoor capability and NEMA 4X enclosure reduce corrosion risk and extend service life. Business Impact → Compliance with washdown and outdoor requirements without special enclosures. Application → Outdoor-rated plant sections and damp environments. Throughout, this transformer supports industry-standard components and offers compatibility with common control-panel architectures, easing procurement and installation while delivering measurable efficiency gains and reduced life-cycle costs.

FAQs

Installation should follow Eaton's recommended mounting orientation and clearance for cooling. Use appropriate isolating hardware and mount the transformer on a non-conductive base or standoffs. Connect 240/480 V primary leads to the disconnect or main bus, and wire the 120/240 V secondary to the control circuits, ensuring proper grounding and compliance with local electrical codes.
Key specs include a 0.15 kVA VA rating, single-phase operation at 60 Hz, primary voltages of 240 V and 480 V, secondary voltages of 120/240 V, and a 115 °C temperature rise. The winding material is aluminum, and the enclosure is NEMA 4X rated for indoor-outdoor use.
Yes. The transformer features a NEMA 4X stainless steel enclosure (Grade 304) designed for indoor-outdoor service, providing protection against moisture, dust, and corrosion in washdown environments common in manufacturing and processing plants.
The unit has a fixed tap size with no external taps (. None). This simplifies installation and reduces the potential for mis-wiring, making it a straightforward solution for standard control-panel voltage requirements.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first.
