摘要： A power circuit breaker is intended to be effectively locked in a simple manner in a withdrawable-part rack. For this purpose, a locking device is provided having a first component, which is fixed in the withdrawable-part rack, and a second component, which is fixed to the power circuit breaker. The first component and the second component do not engage with one another in the inserted position. However, in the event of a short circuit they engage with one another in a tilted position of the power circuit breaker, which position is rotated with respect to the inserted position, with the result that the power circuit breaker is locked in the withdrawable-part rack.

摘要： A power circuit breaker (1) is provided with an arrangement that controls its switching-on depending on operating parameters (A . . . E, M1, M2, S). These parameters may be, for example, the position of switching contacts, the state of excitation of an undervoltage release and the switching position of another power circuit breaker. The arrangement has a coupling shaft (32) that may be rotated by a tripping half-wave by means of a steering lever (34) and by certain parameters by means of a sensor lever (36). A coupling member (20) that may be swivelled by the coupling shaft (32) allows a ratchet device (5, 6) of the energy store (7) of the power circuit breaker (1) to be released only when all conditions required for switching-on are met.

It further includes a switching shaft for transferring drive forces to the at least one switching pole. The switching pole enclosure includes a first and a second enclosure shell, which rest against one another along a separating joint running essentially parallel to the contact plane, and in which the switching shaft is mounted by use of at least two switching shaft mounts held on the first enclosure shell. At least one first and one second fastening device, each serving the purpose of connecting the two enclosure shells, is in each case supported on the one hand on the second enclosure shell and on the other hand on one of the switching shaft mounts.

摘要： A trip device is for an electrical power breaker, for tripping on a short-circuit. It is embodied as an analogue electrical circuit. The circuit components and devices necessary for tripping on a short circuit form a discrete module, completely independent of other trip devices on the power breaker. A direct current is provided by transformers together with rectifiers which flows through a power semiconductor switched to conduct in the normal operating state of the power breaker. A measurement and control circuit is controlled by way of a voltage generated across a measuring resistance through which the direct current flows and closes the power semiconductor when a threshold value is exceeded. The current is then commutated from the power semiconductor to the trip magnet which opens the switch contacts with a particularly small delay.

摘要： A circuit arrangement is disclosed for rapidly switching off low-voltage circuit breakers comprising an electronic tripping unit. According to an embodiment, a switching element which is operated in a short-circuit mode during normal operation and to which a fast trip magnet of the low-voltage circuit breaker is connected in parallel is impinged upon by a current that is proportionate to the current monitored by the low-voltage circuit breaker, and the short circuit of the switching element is bypassed when the current monitored by the low-voltage circuit breaker reaches a set threshold value. One respective transformer is serially connected to the power inputs of the electronic tripping unit, the secondary ends of the transformers being interconnected among each other on the direct voltage side while being serially connected to the switching element via bridge rectifiers.

摘要： A method and a circuit arrangement are disclosed for rapidly switching off low-voltage circuit breakers by impinging a switching element which is operated in a short-circuit mode during normal operation and to which a fast trip magnet is connected in parallel, with a current that is proportionate to the current monitored by the low-voltage circuit breaker while the short circuit of the switching element is bypassed when the current monitored by the low-voltage circuit breaker reaches a set threshold value. The fast trip magnet is at least temporarily short-circuited once again as soon as the monitored current reaches a second given threshold value. A corresponding circuit can be designed such that the switching element is embodied as a switching transistor which can be controlled back into the conducting state by a second monitoring circuit for the current monitored by the low-voltage circuit breaker when a second given threshold value has been reached.
