Eaton CV29M47T45EE General Purpose Transformer - UL Listed
Part Number: CV29M47T45EE
Quick Summary
Eaton CV29M47T45EE transformer delivers reliable general-purpose power conversion for 3-phase electrical systems. In many facilities, voltage mismatches and thermal limits threaten uptime; this unit helps by offering selectable taps and robust insulation. With CSA certification and UL listing, it meets essential safety and compliance standards, while the NEMA 2 enclosure protects in typical plant environments. The 45 kVA rating supports medium-sized automation panels, and its 208 V primary with 480Y/277 V secondary configuration aligns with common industrial loads. Designed for flexible installation in control rooms and switchgear, it provides consistent performance across varying loads and helps reduce panel redesign costs and procurement complexity.

Ventilated design and a 45 kVA three-phase rating deliver robust thermal performance, enabling longer duty cycles and reduced downtime in continuous operation environments. This directly translates to higher plant availability and lower maintenance costs while supporting standard North American 60 Hz power systems. Tap settings include two taps at +2.5% and four taps at -2.5%, which minimizes voltage drop or excess voltage at the load, improving motor starter life and reducing nuisance tripping during voltage fluctuations. The DT-3 topology paired with a Frame 912D provides compact, panel-friendly installation and straightforward wiring, accelerating commissioning for automation panels and switchgear. The enclosure is rated NEMA 2, offering reliable protection in dusty or damp plant spaces, which simplifies siting and reduces enclosure-related maintenance. CSA Certified UL Listed certification reinforces procurement and compliance, streamlining audits and supplier qualification. Additional value comes from the clear 60 Hz operation, 208 V primary and 480Y/277 V secondary outputs, enabling seamless integration with existing PLCs, drives, and distribution blocks. Eaton’s warranty and support policy further de-risks project timelines and ongoing plant reliability, making this transformer a practical choice for panel builders and maintenance teams.

FAQs
Mount the 3-phase unit in a well-ventilated panel with clear access for wiring. Ensure the NEMA 2 enclosure remains intact, provide adequate clearance for heat dissipation, and align primary 208 V and secondary 480Y/277 V connections with standard 4-wire configurations. Use the +2.5% / -2.5% taps to fine-tune voltage under load and verify 60 Hz operation in your facility.
The transformer accepts 208 V on the primary and provides 480Y/277 V on the secondary, rated at 45 kVA. It is suitable for medium-sized automation panels, drives, and distribution blocks that require stable three-phase power in 60 Hz systems.
Yes. It is CSA Certified and UL Listed, which validates safety, performance, and regulatory compliance. This simplifies supplier qualification, reduces third-party testing needs for new installations, and helps meet internal and external audits for industrial electrical equipment.
The taps allow fine-tuning to compensate for supply variations, minimizing under- or over-voltage at the load. This reduces motor wear, improves control stability, and lowers energy losses in variable-load applications common in automation and panel builds.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first. This, combined with Eaton’s technical support, helps manage long-term maintenance costs and supports rapid issue resolution during commissioning and operation.
