摘要

The system has a support block connected to busbars. A hollow tube shaped bar (22) is provided with electrical contacts and slides relative to the support block. One electrical contact is connected to a plug-in connector of an arcing chamber. A semi-automatic type coupler includes balls that cooperate with a groove and a push rod to maintain the bar in a connected position during assembling and disassembling of the contacts. An independent claim is also included for a circuit breaker comprising a connecting system.
