A circuit breaker includes a current entry which conducts an electrical current via a wound coil conductor strip of a first coil to a first fixed contact, and includes a contact rocker which can be moved between two switching positions. The contact rocker includes mutually connected contact limbs. A first switching position of the contact rocker, electrically connects the first fixed contact with a second fixed contact which is connected via a wound coil conductor strip of a second coil to a current exit for dissipating an electrical current flowing through the contact limbs of the contact rocker and the coil conductor strips of the coils to a current exit of the circuit breaker. A high electrical current which flows through the wound coil conductor strips of the coils and through the contact limbs of the contact rocker produces a magnetic field which generates a switching force which moves the contact rocker from the first switching position into a second switching position in which the two fixed contacts are electrically separated to interrupt the electrical current.

A circuit breaking apparatus comprises a circuit breaker, a motor drive system, and a controller. The circuit breaker is electrically connectable to a power line. The motor drive system is mechanically coupled to the circuit breaker and configured to operate the circuit breaker such as to perform a movement including at least an opening movement from a closed position to an open position, thereby electrically interrupting the power line. The controller includes a model of at least one of the motor drive system and the circuit breaker. The controller is configured to receive reference travel curve information of the movement; generate actuator information from the reference travel curve information based on the model; and output the actuator information.

A method and an apparatus for controlling a circuit breaker in an electrical energy supply network. A switching signal is generated by a protective or control device of the energy supply network and the switching signal is transmitted to a control unit of the circuit breaker. The control unit is caused to open the switching contacts of the circuit breaker upon reception of the switching signal. In order to ensure a switching operation which is as fast as possible even in those energy supply networks in which phases of the current to be switched by a circuit breaker which are free of zero crossings can occur, a current flowing through the circuit breaker is recorded and is checked for the occurrence of zero crossings. The transmission of the signal for opening the switching contacts is prevented until at least one zero crossing has been detected.

A method for determining the operating status of a spring charging motor of a LV or MV switching apparatus. The method comprise: acquiring a detection signal (I.sub.D) indicative of the behavior of a driving current (I.sub.MOT), which feeds the spring charging motor during an operation cycle of the spring charging motor; processing the detection signal (I.sub.D) to calculate a steady-state detection signal (I.sub.DSS) indicative of the behaviour of the driving current (I.sub.MOT) during a steady-state time interval (T.sub.SS) comprised in the operation cycle of the spring charging motor; processing the steady-state detection signal (I.sub.DSS) to calculate data (DS) indicative of HF and LF spectral components of the driving current (I.sub.MOT) during the steady-state time interval; processing the data (DS) indicative of the HF and LF spectral components to calculate first and second harmonic distortion values (THD.sub.LF, THD.sub.HF), which are indicative of the total harmonic distortion of the LF and HF spectral components, respectively; processing the first and second harmonic distortion values to calculate first and second output data (O.sub.1, O.sub.2), which are indicative of the variations of the first and second harmonic distortion values with respect to corresponding first and second reference values, respectively.
