Switchgear cabinet arrangement (1a..1f), comprising - a switchgear cabinet - a multipolar input for connecting the switchgear cabinet to a power supply network, - at least one multipolar output, which is used for supplying a device connected thereto with electrical power, - a plurality of electrical conductors (2, L1..L3, N) and a plurality of circuit breakers (3a..3f) arranged in their path, by which the poles of the input can be electrically connected to poles of the at least one output via a first path, - at least one sensor (4a..4c) arranged on one of the electric conductors (2, L1..L3, N) and in the first path, which sensor is configured to detect a measured value for a current flowing through the conductor (2, L1..L3, N) in the first path and/or a measured value for a temperature of the conductor (2, L1..L3, N) in the first path, and - a controller, which is configured to connect the at least one output inside the switchgear cabinet by activating the circuit breaker (3a..3f) via a second path, different from the first path, to the input, when the sensor detects current and the detected current is above a first threshold, and/or when the sensor detects temperature and the detected temperature is above a second threshold, characterised in that - one of the circuit breakers (3a..3f) has an overcurrent trip which is configured to open at least one switching contact of the circuit breaker (3a..3f), when a current over the at least one switching contact is above a third threshold, and the first threshold is below the third threshold and/or - in that one of the circuit breakers (3a..3f) has a temperature trigger which is configured to open at least one switching contact of the circuit breaker (3a..3f), when a temperature of the temperature trigger is above a fourth threshold and the second threshold is below the fourth threshold. - a switchgear cabinet - a multipolar input for connecting the switchgear cabinet to a power supply network, - at least one multipolar output, which is used for supplying a device connected thereto with electrical power, - a plurality of electrical conductors (2, L1..L3, N) and a plurality of circuit breakers (3a..3f) arranged in their path, by which the poles of the input can be electrically connected to poles of the at least one output via a first path, - at least one sensor (4a..4c) arranged on one of the electric conductors (2, L1..L3, N) and in the first path, which sensor is configured to detect a measured value for a current flowing through the conductor (2, L1..L3, N) in the first path and/or a measured value for a temperature of the conductor (2, L1..L3, N) in the first path, and - a controller, which is configured to connect the at least one output inside the switchgear cabinet by activating the circuit breaker (3a..3f) via a second path, different from the first path, to the input, when the sensor detects current and the detected current is above a first threshold, and/or when the sensor detects temperature and the detected temperature is above a second threshold, - one of the circuit breakers (3a..3f) has an overcurrent trip which is configured to open at least one switching contact of the circuit breaker (3a..3f), when a current over the at least one switching contact is above a third threshold, and the first threshold is below the third threshold and/or - in that one of the circuit breakers (3a..3f) has a temperature trigger which is configured to open at least one switching contact of the circuit breaker (3a..3f), when a temperature of the temperature trigger is above a fourth threshold and the second threshold is below the fourth threshold.
