FAQs
For panel installation, start with de-energizing the system and confirming panel clearance for a 564 lb transformer. Connect primary 460 V to the input terminals and secondary 208Y/120 V to the control circuits or drives. Ensure proper grounding, secure mounting to a rigid surface, and follow the Eaton datasheet wiring diagrams for phase balance and short-circuit protection. Use appropriate fusing and wire sizing per the catalog recommendations.
The V52T28T25XNV is specified as a 25 kVA, 3-phase transformer with a 150 C rise insulation profile, suitable for elevated ambient temperatures and limited ventilation. While exact efficiency varies with load and conditions, planning around typical transformer efficiency in the 95%+ range at rated load is common. The non-ventilated enclosure helps minimize external cooling requirements, contributing to stable thermal performance in controlled environments.
Yes. With a 25 kVA rating and 460-208Y/120 V output, it supports PLCs, drives, and other automation gear within control cabinets. The totally enclosed non-ventilated design reduces dust ingress and simplifies maintenance, making it well-suited for crowded, industrial spaces where space and reliability are critical considerations.
Certifications for this model are listed as ‘Contact Manufacturer’ in the spec sheet. For compliance, verify regional electrical safety marks (such as CE) and any site-specific requirements with Eaton or your authorized distributor. Always align transformer selection with your local codes and the safety standards applicable to your facility.
The non-ventilated enclosure reduces dust intake and eliminates moving parts in cooling fans, lowering maintenance frequency and energy usage. This translates to lower operating costs, less scheduled downtime, and extended transformer life in dirty or cramped plant environments. In turn, you gain improved uptime, predictable performance, and a faster return on investment for automation projects.
