Abstract

A switchgear includes a power supply built into a common housing, and at least two drives. The power supply can be fed by an external supply voltage and an external consumer can be connected to the two drives. In at least one embodiment, the switchgear includes, in the same housing, a built-in overload detection for the two drives and/or a built-in circuit breaker function for the two drives, and/or a built-in control circuit for the common control of the two drives. The switchgear can optionally be completed by a transformer providing an additional function of the targeted charging of a buffer capacitor and/or by an energy accumulator providing an additional function of the targeted discharge thereof by temporarily switching on a connected consumer.
