Abstract
A selective circuit breaker, in operation connectable between a main supply line and a downstream circuit breaker, has a bypass switch in a supply line, and a controlled semiconductor switch connected in parallel to the bypass switch. A bypass switch off detection circuitry and a short circuit detection circuitry are provided for controlling the bypass switch and the semiconductor switch in accordance with a switching characteristic. The switching characteristic of the selective circuit breaker is programmable, and a short circuit current rating of the selective circuit breaker is substantially equal to a short circuit current rating of the downstream circuit breaker.
