Eaton V48M22T30CUNV Transformer - UL Listed
Part Number: V48M22T30CUNV
Quick Summary
Eaton V48M22T30CUNV transformer provides reliable three-phase dry-type distribution for control panels. In harsh industrial settings, ventilated or open transformers can allow dust and moisture ingress, compromising performance and uptime. UL Listed certification supports safety compliance, while the DT-3 dry-type design and 150°C rise reinforce reliability across challenging environments. For panel builders and machine integrators, this transformer delivers predictable voltage regulation, a compact footprint, and installation simplicity, enabling efficient power distribution and streamlined maintenance planning. With a 30 kVA rating and copper windings, it also handles peak loads with reduced losses and supports responsive voltage coordination through ±2.5% taps.

FAQs
This unit is a three-phase, dry-type transformer with a 480 V primary and 240/120 V secondary. It features a 914DN frame and a weight of 591 lb, so plan for a robust mounting base and appropriate hoisting methods. Ensure access to the taps at +2.5% and -2.5% for voltage adjustment during commissioning and load changes.
Key specs include a 30 kVA rating, 60 Hz operation, copper windings, and a 150°C rise. The DT-3 enclosure provides a totally enclosed, non-ventilated design, reducing dust/moisture ingress. Primary 480 V and secondary 240/120 V support standard industrial controls and machine applications.
Yes. The V48M22T30CUNV is designed for indoor, enclosure-based power distribution in control panels and machine integrations. Its dry-type, totally enclosed construction minimizes environmental exposure, while the 30 kVA rating supports a range of control loads with reliable regulation and fast response to load changes.
The unit is UL Listed, confirming compliance with recognized safety standards for electrical equipment used in distribution and control applications. This certification facilitates procurement within regulated facilities and simplifies safety documentation for audits and inspections.
The product follows Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. Maintenance is typically minimal due to the enclosed dry-type design; routine checks focus on enclosure cleanliness, tap position accuracy, and connection integrity to sustain voltage stability.
