Abstract
A combination converter arrangement and a switching device including such a combination converter arrangement are disclosed. The combination of a current transformer with a core made of ferromagnetic material and a Rogowski coil is referred to as a combination converter, the current transformer being used to supply energy to the electronic tripping unit of the switching device, and the Rogowski coil being used to measure current. In order to make use of the installation space available in the switching device for installing combination converters, a plurality of combination converters are arranged in a common housing to thereby provide a multi-pole combination converter module.
