Switchgear having - a processor which is set up to generate a control signal and - an on/off switch which is coupled with the processor in terms of data, comprising: - an electronic switchgear which is switchable by means of the control signal between a first state ON and a second state OFF; - a digital line protection circuit which is set up, with the help of a line protection function, - to implement an over-current shutdown when a given current determined by means of the current metering device exceeds a threshold value, and - to implement a short-circuit current shutdown when a short-circuit current is determined by means of the current metering device; - a bus line which is set up to transmit data to the processor; - a manual switchgear with which the on/off switch is switchable between the first state ON and the second state OFF; and - a switch actuator function with which the on/off switch is remotely switchable between the first state ON and the second state OFF via the processor, wherein the processor in this case is coupleable with an external data processing device, so that a signal is transmittable from the external data-processing device to the processor, from which the processor generates the control signal. - a processor which is set up to generate a control signal and - an on/off switch which is coupled with the processor in terms of data, comprising: - an electronic switchgear which is switchable by means of the control signal between a first state ON and a second state OFF; - a digital line protection circuit which is set up, with the help of a line protection function, - to implement an over-current shutdown when a given current determined by means of the current metering device exceeds a threshold value, and - to implement a short-circuit current shutdown when a short-circuit current is determined by means of the current metering device; - a bus line which is set up to transmit data to the processor; - a manual switchgear with which the on/off switch is switchable between the first state ON and the second state OFF; and - a switch actuator function with which the on/off switch is remotely switchable between the first state ON and the second state OFF via the processor, wherein the processor in this case is coupleable with an external data processing device, so that a signal is transmittable from the external data-processing device to the processor, from which the processor generates the control signal. - an electronic switchgear which is switchable by means of the control signal between a first state ON and a second state OFF; - a digital line protection circuit which is set up, with the help of a line protection function, - to implement an over-current shutdown when a given current determined by means of the current metering device exceeds a threshold value, and - to implement a short-circuit current shutdown when a short-circuit current is determined by means of the current metering device; - to implement an over-current shutdown when a given current determined by means of the current metering device exceeds a threshold value, and - to implement a short-circuit current shutdown when a short-circuit current is determined by means of the current metering device; - a bus line which is set up to transmit data to the processor; - a manual switchgear with which the on/off switch is switchable between the first state ON and the second state OFF; and - a switch actuator function with which the on/off switch is remotely switchable between the first state ON and the second state OFF via the processor, wherein the processor in this case is coupleable with an external data processing device, so that a signal is transmittable from the external data-processing device to the processor, from which the processor generates the control signal.
