ABSTRACT:
A circuit breaker for multi-phase power includes an opening-closing apparatus configured to open and close each phase of the multiphase power, a detection unit configured to detect a fault current in at least one phase of an electrical installation, a plurality of connecting bars disposed on a load side of the circuit breaker, and a fastening device disposed on the connecting bars and configured to detachably fasten a short circuiter to the connecting bars, the short circuiter configured to create a short circuit between the connecting bars when a fault is detected by the detection unit. The option proposed according to the invention of installing a short circuiter means that the circuit breaker is fully operational, either with or without the installation of a short circuiter.
