Embodiment Construction

[0034] figure 1 A switching device 10 is shown in .

[0035] The switching device 10 is a circuit breaker. For example, the switching device 10 is a three-phase circuit breaker.

[0036] In a variant, the switching device 10 is a switch such as a three-pole switch or a four-pole switch.

[0037] The switching device 10 comprises a housing, at least one switching device 15 , at least one trip 20 and a control device 25 .

[0038] In a variant, the switching device 10 comprises a plurality of switching devices 15 . In particular, when the switchgear 10 is a three-phase circuit breaker, the switchgear 10 comprises three switchgears 15, one for each phase.

[0039] Instead of this or in addition, the switching device 10 comprises a plurality of trips 20 . according to figure 1 As an example, the switchgear 10 includes two trips 20 .

[0040] Each trip device 15 comprises an input connection terminal 30 and an output connection terminal 35 .

[0041] The switching device 15...

Abstract

The invention relates to a switchgear (10) comprising: a housing defining a plurality of spaces, each capable of housing a trip (20A, 20B) including a tripping device (40); a switchgear (15); and a control mechanism (25) comprising means (45) for gripping, said means being movable by an operator between a first position and a second position in order to control said switching means (15) between an open position and a closed position movement between, when said means for gripping (45) is in the second position, the switching means (15) is in the closed position, and when the means (45) is in said first position, the switching means (15) in the disconnected position. The control mechanism (25) includes a single reset device (55) configured to reset each trip (20A, 20B) when the operator moves the device (45) from the first position to the second position.

Description

technical field [0001] The invention relates to a switching device. Background technique [0002] Many switching devices include a switching device and a control device adapted to open or close the switching device and thereby prevent or allow current to pass through the switching device. In particular, the control means make it possible to open or close the switching means according to precise specifications, in particular with regard to the rapidity of opening. [0003] Such switching devices often include one or more trips. A trip is a module that enables command opening in the event of an electrical fault being detected (for example, if a voltage is above or below a predetermined threshold, or a short circuit or current draw). [0004] In the event of detection of such a fault, the tripped mobile part moves from the initial position to the tripped position so as to actuate the control device and thus trip the switches of the switching device. Therefore, when this type...
