INFORMATION

Description

The transformers of the MC1 range are efficient current transformers. This range of transformers offers a measurement range from 150...2,000 A. They operate with a 250 mA secondary and feature 3 measurement ranges in the same transformer: simply changing a connection cable and the ratio selected in the measurement unit. MC1 transformers are only compatible with CIRCUTOR’s MC range.

Applications

  • In installations where the electric supply can be interrupted to install transformers.
  • Very useful for installing in places where the exact nominal current range is not known.
