FAQs
The MD660E93 is a 660 kVA dry-type, three-phase transformer with a 460 V to 575Y/332 V configuration. Plan for adequate ventilation, proper clearance for heat dissipation, and accessible maintenance access. Verify correct phase rotation, secure mounting, and configure taps at +5% and -5% FCAN/FCBN to match bus voltage during commissioning.
By delivering true drive isolation, the MD660E93 reduces voltage transients and EMI that can cause motor trips and drive faults. Its 150 °C rise rating and aluminum windings support reliable operation under demanding loads, while the ventilated design keeps temperatures in check. This translates to fewer unplanned outages and more predictable automation performance.
Yes, the MD660E93 can be integrated where 460 V input and 575Y/332 V secondary outputs are compatible with existing motor drives. Its DT-3 dry-type design and positive tap options help accommodate voltage variations. Ensure panel space, cooling, and clearance meet installation requirements, and verify coordination with existing protection and control schemes.
The MD660E93 carries UL Listed certification, confirming safety standard compliance for industrial transformer installations. This simplifies audits and regulatory approvals in manufacturing environments. The design also supports standard industry practices for dry-type drive isolation transformers used in motor control centers.
Maintenance is typically minimal due to the dry-type, ventilated construction and aluminum windings. The 660 kVA rating enables consolidation of multiple smaller units, reducing footprint and installation costs. Improved reliability and reduced downtime contribute to a favorable return on investment, particularly in high-demand automation lines.
