Current transformer multict KBR

Teilbarer Kabelumbau-Stromwandler Typ KBR

Cable type current transformers multict KBR

Current transformer with divisible measuring core for primary rated currents from 50 A to 5,000 A, secondary rated current 5 A or 1 A, in accuracy classes 0.5, 1 and 3.

The divisible measuring system enables easy retrofitting in existing systems with minimum installation effort.

For installation, the locking mechanism on the transformer is opened, placed around the primary conductor and audibly engaged again. After connecting the secondary conductors, the measuring arrangement is ready for operation immediately.

Highlights

  • Cable type current converters are mainly used for retrofitting to prevent primary conductors from separating
  • Straightforward and secure attachment
  • Due to their dimensions and ease of use, they are particularly suitable for use in hard-to-reach places or when space is limited.
  • Thanks to the "click" system, single-handed fitting is possible
  • Available with secondary current 5 A/1 A
  • A total of eight different designs in the KBR series
