Current transformer module with phase changing circuit and switching device equipped with such a module

摘要

The module (6) has inputs (61-66) with fixed switching pieces (68), and outputs (71-73) for connecting an electrical load e.g. electrical machine such as three-phase electric motor. The inputs are interconnected with the outputs by a phase changing wiring (32) and an output-sided phase conductors (67). The output-sided phase conductor is guided through three current transformers (46). Pin or socket terminal strips are interconnected with the current transformer. An independent claim is also included for a switching device for reversing a rotation direction of a electrical consumer.
