Abstract:
A group protection module for a switchgear arrangement is provided in order to protect a group of load feeders, each having a contactor for connecting or disconnecting a respective load. The group protection module has a circuit breaker for providing short-circuit protection, said circuit breaker being connected to a supply-side input and to a load-side output of the group protection module for connection to a power supply system and for connecting the group of load feeders. The group protection module has a safety evaluation unit via which the circuit breaker can be tripped if a status signal detectable by the respective load feeders indicates that one of the contactors of the load feeders can no longer be de-energized. The group protection module is implemented as a constructional unit.
