Current transformer multict KBU

 

Aufklappbarer Kabelumbau-Stromwandler multict KBU

Foldable cable type current transformers multict KBU

Current transformer with divisible measuring core for primary rated currents from 100 A to 5000 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.
