Abstract
A current measuring device for a multi-pole voltage circuit breaker includes a support body with a through opening for a current conductor for each of the poles and a receiving chamber, surrounding the through opening for secondary components of current sensors and/or current transformers. The support body is essentially plate-like and rectangular and forms part of the rear wall of the circuit breaker. Should Rogowski coils be used as secondary components of a transformer, then adjustable voltage dividers are also mounted on the support body for interdependent adjustment. The multi-pole current measuring device simplifies the production of circuit breakers as approved components.
