Abstract: An electronic circuit breaker having a control unit and a controllable semiconductor switch which is connected in a current path between a voltage input and a load output, wherein the semiconductor switch is integrated into a voltage-controlled current source circuit, the output current of said current source circuit when the load is connected being adjusted by means of the control unit in such a way that the power of the semiconductor switch is lower than or equal to a maximum power value, and wherein the control unit outputs a setpoint value to the voltage-controlled current source circuit and receives a difference value from said voltage-controlled current source circuit, which difference value is formed from a deviation of an actual value, which represents the output current, from the setpoint value and is supplied to the semiconductor switch as a control signal for driving said semiconductor switch.

Abstract: A power distributor having a first controller and having a number of connection modules which are connected thereto and are intended to be mounted on a supporting rail. The connection module has a number of lateral coupling contacts for the electrical and/or signalling contact connection to at least one further connection module which is attached or can be attached to the particular connection module, wherein a base resistor is connected in each case between two coupling contacts inside the module in such a manner that the base resistors of the attached connection modules form a resistor chain which is connected in series. The connection modules are each equipped or can be equipped with an actuatable circuit breaker. The circuit breakers have a second controller inside the circuit breaker for recording a voltage dropped across the respectively associated base resistor.

Abstract: An electronic circuit breaker contains a first semiconductor switch which is switched into a current path between a voltage input and a load output and contains a controller which is connected to the control input of the first semiconductor switch. The first semiconductor switch is actuated depending on an actual value of the load current, the actual value is supplied to the controller, and the controller is configured to limit the current of the first semiconductor switch and disconnect same.

Abstract: An electronic circuit breaker with a semiconductor switch, a drain connection and a source connection of the semiconductor switch being connected between a voltage input and a load output, and a gate connection of said semiconductor switch being connected to a control device which is supplied, at the input end, with a signal which represents the load current. The control device determines the drain-source voltage and, from this and from the detected load current, generates a control signal which is routed to the gate connection of the semiconductor switch and by means of which the power of the semiconductor switch is adjusted to less than or equal to a maximum power value.
