摘要： A switching device, in particular a circuit breaker, is disclosed including a switching shaft for mounting a rotary contact link with two switching contacts and a pair of fixed contacts, which pair interacts with the rotary contact link, for connection to in each case one current path. The fixed contacts and the current paths are designed in such a way that the rotary contact link is rotated from a closed position in the direction of an open position in the event of an overcurrent or a short circuit. The switching shaft has a transversely running cutout for mounting the rotary contact link, which protrudes on both sides out of the switching shaft. The rotary contact link is connected, via at least one spring element, to the switching shaft for applying a contact force in the closed position and for the rotary contact link to remain in the open position. According to at least one embodiment of the invention, the rotary contact link has at least one groove-shaped longitudinal cutout, arranged within and along the transversely running cutout in relation to the switching shaft. Two grooves, which are arranged radially opposite one another, with in each case a bent or arcuate profile are provided in the cutout of the switching shaft, the respective two ends of the grooves being positioned radially further outward than the respective central region thereof. In each case one groove is connected to the at least one groove-shaped longitudinal cutout via a transverse bolt guided therebetween. At least one prestressed spring element is provided which pushes the respective transverse bolt radially outward.

摘要： A switch has at least one fixed and one moving contact located on a contact arm. The fixed contact is connected to a loop-shaped conductor segment, such that when current flows through the conductor segment, there is an electrodynamic magnetic force which acts on the contact arm. The force, above a specified current intensity, results in an opening movement of the contact arm. To open the moving contact more rapidly and in a simple manner the loop-shaped conductor segment is realized so that it is wound in a coil shape, and consists of at least two turns, and that the coil axis of the coil segment runs perpendicular to the longitudinal axis of the contact arm.

摘要： A load breaking switch including a rotor embodied as a switch shaft segment, and a contact arm pivotally mounted in the rotor pivotable between an ON and OFF position about an axis of rotation and at the free end of which is a contact piece which is pivotable with the contact arm and is in contact with an opposite fixedly arranged contact piece when the contact arm is in its ON position. Current flows through the switch via the contact pieces and the contact arm. The contact arm is pivotable into its OFF position when the current flowing via the contact pieces exceeds a rated current value or an overload current value. A magnetizable area is spatially arranged inside the rotor such that the current flowing through the contact arm in this area induces a magnetic field which exerts a torque on the contact arm.

摘要： A switch is disclosed. In at least one embodiment, the switch is a load breaking switch including a rotor which is embodied in particular as a switch shaft segment, and a contact arm which is pivotally mounted in the rotor and is pivotable between an ON and OFF position about an axis of rotation and at the free end of which is a contact piece which is pivotable together with the contact arm and is in contact with an opposite fixedly arranged contact piece when the contact arm is in its ON position. In at least one embodiment, the current flows through the switch via the contact pieces and the contact arm, wherein the contact arm is pivotable into its OFF position when the current flowing via the contact pieces exceeds a value, in particular the rated current value or an overload current value. In order to provide a load breaking switch which is simple in terms of its construction and at the same time has a high current-carrying capacity, it is proposed in at least one embodiment that a magnetizable area is spatially arranged inside the rotor in such a way that the current flowing through the contact arm in this area induces a magnetic field which in turn exerts a torque on the contact arm.

摘要： A arcing chamber housing is disclosed for a circuit breaker with a double turning contact breaker. The arcing chamber housing (1) is composed of two housing modules (2, 3) and an extinguishing chamber (19) is arranged in the area of the fixed contact pieces (6, 7) to extinguish the arcs which are formed between the contact pieces of the double turning contact breaker. In order to obtain a arcing chamber housing (1) which is easy and economical to produce, with extinguishing chambers (19) which have a reproducible extinguishing behavior once the arcing chamber is assembled, the two housing modules (2, 3) are substantially L-shaped parts whose inner marginal surfaces (4, 5) face each other. The first parts (17, 18) of the housing, which correspond to the first branches of the L-shaped housing modules (2,3), are designed as extinguishing chambers (19). Also disclosed are the housing modules (2, 3) used to produce such a arcing chamber housing.
