Abstract
Perfections introduced in a protection circuit breaker against fault currents, with a summation current transformer arranged, together with the electrical part of the test arrangement, on a support piece, a trip with control mechanism and groups of contacts, characterized in that a base plate carrying the summation intensity transformer, the test arrangement, the connection terminals and the fixed contacts for a control slide driven on it in a displaceable manner, is made as insertion part for a upper part of the box in which it is retained by a lower part of the lockable box with the upper part of the box; because, in addition, on the partition of the upper part of the box there are provided passage openings and guide openings for the test pushbutton and a driving pin which is located on the control slide, and above the partition, the part the upper part of the box has a housing for receiving the control mechanism, the control mechanism being retained in the housing by a cover having through openings and which can be locked with the upper part of the box.
