  • Patent number: 7974058
    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.

  • Patent number: 7884298
    Abstract: A switch for a switching unit for energy supply and distribution includes a first connection and a second connection, each with a cylindrical bolt. The bolts are axially adjacent one another and spaced apart. An annular sleeve with an inner diameter larger than the diameter of the bolts, is arranged in such a way that it can be axially displaced on the bolt of the first connection, and partially on the bolt of the second connection. At least a first contact element is arranged between the surface of the bolt of the first connection and the inner surface of the annular sleeve. At least a second contact element is arranged and constructed in such a way that it can be positioned between the surface of the bolt of the second connection and the inner surface of the annular sleeve.
