Abstract
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.
