Eaton T52M11S15CUNV Dry-Type Transformer - DS-3
Part Number: T52M11S15CUNV
Quick Summary
Eaton T52M11S15CUNV Dry-Type Transformer reliably conditions 460 V primary to 120/240 V secondary for on-site power distribution. This unit targets compact, panel-ready installations where space and heat management matter. Many facilities struggle with heat, maintenance, and enclosure constraints from larger vented transformers; a totally enclosed, non-ventilated design helps simplify cooling and enclosure planning. Certifications typically expected for industrial transformers include CE safety listings and UL/CSA marks, with IP ratings tied to the enclosure—verify specific approvals with the manufacturer. In practice, this transformer delivers robust performance, with copper windings and adjustable taps supporting voltage stability and lower operating costs in machine controls and distribution panels.

FAQs
Install on a flat, level base using compatible mounting hardware for the 818N frame. Connect the 460 V primary to the hot leads and the 120/240 V secondary to the downstream panels. Verify enclosure suitability for 150°C rise and ensure space for taps. The unit’s compact design supports integration into standard control cabinets with minimal rearrangement.
The T52M11S15CUNV offers 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN, enabling fine-tuning of output to maintain stable downstream voltages. This reduces nuisance tripping and equipment stress when the input voltage drifts, improving overall automation reliability in panel boards and machine controls.
Yes. With 15 kVA, single-phase operation, copper windings, and 120/240 V secondary, it suits mid-load control panels and automation peripherals common in packaging and machine tools. The DS-3 design supports compact enclosures, while taps help accommodate supply variance seen in factory environments, delivering consistent performance for automation circuits.
Certifications are listed as ‘Contact Manufacturer’ for this model. In practice, industrial transformers of this type are typically aligned with CE safety standards and UL/CSA safety listings, with enclosure IP ratings available per application. Always confirm the exact certifications with Eaton or your distributor to meet local regulatory requirements.
The unit is backed by Eaton’s one-year warranty from installation or eighteen months from shipment. Copper windings and a sealed enclosure reduce maintenance needs, lowering lifecycle costs. Plan routine inspections for insulation integrity and ensure taps are checked during commissioning to sustain voltage accuracy and minimize unexpected downtime.
