    Abstract: A method includes receiving a first set of operational parameters that correspond to one or more semiconductor devices of a solid-state circuit breaker and sending a first command to the solid-state circuit breaker to turn off the one or more semiconductors in response to the first set of operational parameters exceeding a first set of thresholds. The method includes sending a second command to the solid-state circuit breaker to turn on the one or more semiconductors in response to the first set of operational parameters being equal to or less than the first set of thresholds. The method includes receiving a second set of operational parameters that correspond to one or more electrical properties associated with an operation of the solid-state circuit breaker coupled to a load device and generating a baseline profile representative of the first set of operational parameters and the second operational parameters.

    Abstract: Ground-fault circuit interrupter positioned between energy controlled supply circuit and load circuit which includes fault detection circuit that senses ground path current leakage to the load circuit, fault processing circuit that detects presence of fault and generates fault output signal when fault detected, and control circuit switch connected to fault processing signal output, wherein control circuit switch is opened by presence of fault output signal, thus isolating load circuit from supply circuit. Preferably fault processing circuit and control circuit are optically linked, such that when fault is detected, control circuit switch is opened by optical fault output signal, thus isolating load circuit from the supply circuit. Circuit interrupter may couple another circuit interrupter via power distribution control unit, optionally manageable remotely via automated control interface.

    Abstract: A device for monitoring a current in a primary conductor with respect to a predetermined current threshold, comprising: a magnetic circuit associable to the primary conductor and comprising a fixed part and an element which can rotate about a rotation axis; at least one spring operatively connected to the rotating element for keeping it in a first position, the spring being elastically deformable along a linear axis; and sensing means operatively associated to the magnetic circuit. The magnetic circuit is configured in such a way that the rotating element rotates from the first position to a second position when the current in the primary conductor exceeds the predetermined current threshold, so as to at least reduce one or more air gaps between the rotating element and the fixed part and to elongate the spring from a first length to a second length. The sensing means are configured for generating an output electrical signal caused by the rotation of the rotating element from the first position to the second position.The at least one spring is operatively connected to the rotating element in such a way to tilt towards the rotation axis moving above a surface of the rotating element which is transversal to the rotation axis, during the rotation of the rotating element from the first position to the second position.

    Abstract: The invention discloses a short circuit current hierarchical control tripping parameter circuit breaker. According to the invention, resistance of an alloy magnetic resistance body is changed through circuit current, and contract control can be carried out on short-circuit current. The control range of the circuit breaker can achieve that no magnetic resistance will be generated when current is no more than 8 times of rated operational current, and current limiting may be realized by the magnetic resistance when current is 8 times more than rated value. In this way, hierarchical control on short-circuit current of different levels of circuits can be carried out, and short-circuit current can be limited in a predetermined range, thereby restricting the short-circuit current in a predetermined range, solving a problem of power supply flickering, and avoiding large-area power failure accidents caused by override trip existing in an electrical control switch.

    Abstract: A circuit breaker is disclosed for an electrical circuit. The circuit breaker includes a tripping unit; at least one current sensor; and an input for a signal, at which a blocking signal for a circuit breaker arranged upstream on the energy sink side, can be received. The tripping unit; at least one current sensor; and an input are all connected to a control unit. A connectable blocking function is provided. The ascertained current is compared with a first current limit value, the exceeding of which requires this first current value to be present for a first period of time in order to prompt interruption of the electrical circuit; and is compared with a second current limit value. Different periods of time need to be present to prompt interruption when the blocking function is disengaged or engaged.
