DTA Transformers

Product catalog summary
Overview: This document provides technical specifications and ordering information for three-phase starting autotransformers, specifically the DTA series, designed for starting three-phase asynchronous motors.
Specifications:
  • Compliance with standards: IEC/EN 61558-2-13, EN 60076-1, VDE 0570-2-13.
  • Insulation class: B.
  • Ambient temperature range: -25 to 40°C.
  • Connection terminal: <63 A.
  • Frequency: 50/60 Hz.
  • Rise time: <15 seconds.
Additional Features:
  • Additional tapping options available (refer to page 59).
  • Temperature control options (refer to page 61).
Product Variants: The document lists various models (DTA0.8 to DTA20) with specifications such as starting frequency, dimensions, and weight. Each model has a specific rated output, motor output, inrush current, and voltage ratings.
Ordering Information:
  • When ordering, specify the rated input voltage with the type designation (e.g., DTA0.8(400)).
  • Material surcharge details are available on page 64.
  • Custom specifications or taps are available upon request.
Important Notes:
  • The design is applicable only for unloaded starting.
  • The motor should consume a starting current of max. 4.5 x In at the indicated rated output voltage.
