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.

摘要： A switching gas damper is for low voltage power switches, especially for low voltage power switches which can be inserted into low voltage switching installations. The switching gas damper is arranged above an arc extinguisher of the low voltage power switches and includes at least one inlet for switching gases and at least one outlet for damped deionised switching gases. The switching gas damper is provided with a carrier element which can be arranged directly adjacent to the arc extinguisher and can be fixed to a housing receiving the low voltage power switch. The carrier element forms at least one receiving chamber for a flow element creating a flow resistance for the switching gases, and the at least one receiving chamber can be closed by at least one closing element fixing the at least one flow element. The carrier element forms the at least one inlet and the at least one closing element forms the at least one outlet.

摘要： An air guidance device is for cooling a switch part of an electrical switch. It includes at least one air guidance element arranged at a distance from the switch part to be cooled, forming at least one air duct which runs vertically when the switch is in the installed position. The air duct includes an inlet area, which points downwards, for cooling air to flow therein, and having an outlet area, which points upwards, for cooling air to flow out thereof. In order to improve the heat dissipation, the air guidance element is shaped such that the inlet area tapers in the direction of the outlet area.
