Abstract
A contact system for current limiting units which are combined with power circuit breakers or motor circuit breakers. The object of the invention is to improve the reliability of the current limiting unit equipped with such a contact system, while reducing the time and effort required to assemble and install such a contact system. The invention teaches that the contact systems can be assembled from a contact carrier with a stationary contact tip and a subsystem preassembled with little force, which can be installed in the arcing chambers in a stable condition and under the force of contact compression springs. The subsystem contains the wiper provided with the moving contact tip, which wiper is mounted with a direct electrical connection to a supply lead. Supports in the subsystem limit the movement of the wiper in both directions. A support block provided with a holding groove and auxiliary groove for the non-positive assembly of the parts connected to the contact compression springs makes it possible to preassemble the subsystem by means of an intermediate state which is also stable.
