ASK 31:3 Type Current Transformer for Indirect Measurement of Sinusoidal AC

  • 1715v-ask31-3_persp2.jpg

Bushing-type current transformers are slipped over the primary conductor. Time consuming wiring is eliminated. The secondary side (as a rule a measuring instrument, a display or a controller) is connected via terminals. Bushing-type current transformers are available with ratings as of 75 A in various sizes for busbars and cables.
