Dispositif de déclenchement brusque pour l'ouverture automatique d'un appareil interrupteur et pour son réarmement local manuel ou télécommandé. Le dispositif comprend un organe de transmission (3) associé à un premier et à un second mécanisme à déclenchement brusque, où ce dernier comprend un levier de déclenchement (20) coopérant avec l'organe (3), avec un levier de verrouillage (10) du premier mécanisme et avec un levier de réarmement distinct (35). Un tel dispositif est avantageusement appliqué aux appareils contacteurs à ouverture automatique qui possèdent un organe de commande locale pour la fermeture, l'ouverture et le réarmement.

L'invention concerne un dispositif de commande du déplacement d'un bras entre une position d'arrêt et une position de service. Ce dispositif comprend un organe (4) de commande (5) par l'intermédiaire d'un élément de transmission (5b) pouvant être constitué par une extrémité d'une biellette (5) ainsi qu'un dispositif de verrouillage (7) déplaçable entre une position verrouillée et une position déverrouillée. Ce dispositif est applicable comme interrupteur, présente un nombre de pièces réduit et est d'une grande facilité de montage.
摘要:
The invention relates to the field of low-voltage electric appliances, and more particularly, to a miniature circuit breaker, which includes a button mechanism, a circuit breaker housing, and an anti-switching-on mechanism, wherein the button mechanism is arrange at one end of the circuit breaker housing and is in sliding fit with the circuit breaker housing, the anti-switching-on mechanism includes a first locking member, the first locking member is pivotally arranged on the circuit breaker housing, one end of the first locking member is in locking fit with the button mechanism to prevent the button mechanism from moving towards a switching-on direction, and after the miniature circuit breaker is assembled to an assembly position of the circuit breaker and installed in place, a housing at the assembly position of the circuit breaker acts on the first locking member, so that after the first locking member is unlocked from the button mechanism, the button mechanism is capable of moving towards the switching-on direction for a switching-on operation; and according to the miniature circuit breaker of the invention, the anti-switching-on mechanism thereof ensures that the miniature circuit breaker is capable of being switched on only after being assembled to the assembly position of the circuit breaker and assembled in place, thus ensuring the use safety.

Switches with integrated overcurrent protection elements are described. The overcurrent protection elements can include a bimetallic structure which is configured to move between a first shape and a second shape in response to heating. The overcurrent protection element can be rotationally coupled to a rotary knob in some embodiments. In other embodiments, the overcurrent protection element can be fixed, and the rotary knob can be connected to one or more rotatable conductive structures within the rotary switch.

An electrical switching apparatus, such as a subminiature circuit breaker (2), includes a housing assembly (4), separable contacts (6), an operating mechanism (8) having an actuator device (14) and a latching assembly (40), a first trip device (10) for tripping open the separable contacts in response to an overcurrent condition, and a second trip device (12) for tripping open the separable contacts (6) in response to an arc fault, a ground fault or a remotely transmitted signal. The subminiature circuit breaker (2) includes a reset solenoid (50) and a trip solenoid (60). The resent solenoid (50) is coupled to the actuator device (14), and includes a coil (52) operable to electrically reset the separable contacts (6). The trip solenoid (60) is coupled to the latching assembly (40), and includes a coil (52) operable to move the catch lever (42), thereby electrically tripping open the separable contacts (6).
