FAQs
MD63E95 is designed for three-phase 575 V primary supply and 460Y/266 V secondary outputs, aligning with standard drive and motor control panels. Its DT-3 dry-type construction and aluminum windings support straightforward integration in typical industrial electrical rooms with compliant ventilation and mounting clearances.
Confirm three-phase, 60 Hz operation; primary 575 V; secondary 460Y/266 V; tap settings at +5% and -5% FCAN/FCBN; and 63 kVA VA rating. Check the mounting footprint (22 in depth, 29 in width, 39 in height) and weight (approximately 506 lb) to ensure proper rack or cabinet space and structural support.
Yes. The MD63E95 is purpose-built as a drive isolation transformer for VFD-driven loads. Its ventilated dry-type design, UL Listed safety certification, and 63 kVA rating support reliable isolation for motors and drives in packaging and conveying equipment, helping reduce electrical noise and voltage-induced tripping.
The MD63E95 carries UL Listed certification, confirming compliance with relevant safety standards for industrial power equipment and motor control applications, which aids in audit readiness and system safety validation.
With aluminum windings, WS39 weather shield, and a 150 °C rise rating, the unit is built for durable operation in demanding environments. A one-year warranty (or 18 months from shipment, whichever occurs first) provides initial protection, while its solid construction reduces maintenance costs and downtime, contributing to a favorable return on investment over the equipment life cycle.
