Abstract
An earth-leakage current circuit breaker, whose summing current transformer (1) is arranged on a base (2) under which the switching contacts (3) are located. It is provided that braided conductors (4) for the electrical connection between the switching contacts (3) and primary conductors (5) which are passed through the annular core (6) of the summing current transformer (1) are connected to solid connecting angle elements (7) which are plugged through slots (8) in the base (2) and are positioned by bending, the primary conductors (5) of the summing current transformer (1) being connected to the positioned connecting angle elements (7). <IMAGE>
