Dry-type, ventilated DT-3 design provides safe, maintenance-friendly cooling with no oil, reducing fire risk and enabling indoor or semi-outdoor installations. This translates to lower lifecycle costs and easier compliance for industrial control rooms across manufacturing facilities. The three-phase, 60 Hz configuration with a 208 V primary and 460Y/266 V secondary delivers consistent drive voltage, minimizing nuisance tripping and extending inverter life in variable plant conditions. Copper windings offer high efficiency and reduced copper losses, supporting reliable operation under peak motor loads and enabling slimmer energy footprints for motor drive systems. The 93 kVA rating accommodates significant drive power while maintaining compact form factors, and the taps at +5% and -5% provide voltage flexibility to match plant supply variations without additional equipment. With a frame of 916A and a footprint derived from 23.42 in depth, 28.22 in width, and 48.56 in height, installation is predictable within standard switchgear or control panels. WS19 Weathershield protection extends outdoor or harsh-environment viability, reducing enclosure requirements and rework. UL Listed certification adds confidence for compliance teams and procurement, ensuring the solution meets essential electrical safety standards for industrial equipment. From a technician’s perspective, the modular design and clear labeling ease commissioning and future scalability, supporting long-term ROI through reduced maintenance time and predictable performance in dynamic production lines.
