Definitions

the present application relates to a modular differential circuit breaker.
Circuit breakers of this type may comprise at least one cut-off compartment and a differential protection compartment, the cut-off compartment (s) having a mechanism for opening and closing at least one electrical contact between an upstream electrical line. and a downstream power line.
Differential circuit breakers may include test functions to test the proper functioning of the differential protection compartment.
the differential protection compartment then comprises a test circuit, the test circuit comprising a first switch that can be closed by pressing a test button
This test can be done by pressing the test button which has the effect of closing the test circuit which simulates a differential fault which causes the tripping of the differential module of the product, generally this differential fault is achieved by a leakage current between the neutral and at least one phase of the product, the current passing through a resistor having the effect of limiting the leakage current.
the circuit breaker comprises a connecting piece mounted inside the differential protection compartment and which makes it possible to mechanically connect the one or more compartment (s) of cutoff between them with at least one lateral lug, preferably two lateral lugs .
the connecting piece can protrude from either side of the differential protection compartment and can penetrate the breaking compartments located, where appropriate, on either side of the differential protection compartment.
the connecting piece can actuate the opening of the contact of the compartments of cuts during a differential defect by means of its lateral pins.
Such a circuit breaker known from the prior art is for example disclosed by the document EP0948021 B1 .
circuit breakers known in the prior art have the drawback of leaving the test circuit active after mechanical opening of the contacts of the breaking compartments and / or after a fault. differential, and thus let unnecessarily pass the current in the test circuit during a long press on the test button, which could result in the destruction of the test function by damaging a resistance of the test function.
the application proposes a differential circuit breaker comprising a test circuit comprising a first switch that can be opened and / or closed by pressing a test button and a second switch that can be opened and / or closed by a part link.
the connecting piece closes the second switch when the contact of the compartment (s) cutoff (s) is (are) closed (s).
the connecting piece opens the second switch when the contact of the compartment (s) cutoff (s) is (are) open (s).
the connecting piece can deactivate the test circuit during mechanical opening of the breaking compartments and / or by the differential protection compartment during a differential fault.
the connecting piece can be adapted to allow the establishment of good contact of the test circuit in the differential compartment, that is to say to close the test circuit (second closed switch, possibility of performing the test function).
the connecting piece physically opens the test circuit (second switch open and thus protects it from a short circuit in case of prolonged support and closure of the test button contact). Indeed when pressing the test button, the first switch test button is closed but as the second switch is open, the test function is disabled.
the connecting piece can deactivate the test circuit during mechanical opening of the breaking compartments and / or by the differential protection compartment during a differential fault.
the first switch and the second switch are connected in series.
the second switch comprises a first contact element and a second contact element, the connecting piece being able to move the first contact element away from the second contact element to open the second switch by bearing against the first element of contact.
the first contact element being rotatably mounted in a case of the differential circuit breaker.
the application relates to a circuit breaker 210 comprising a test circuit comprising a first switch 220 that can be opened and / or closed by pressing a test button 222 and a second switch 230 that can be opened and / or closed by a connecting piece 250.
the connecting piece 250 closes the second switch 230 when the contact of the compartment (s) cutoff (s) is (are) closed (s).
the connecting piece 250 opens the second switch 230 when the contact of the compartment (s) cutoff (s) is (are) open (s).
the first switch 220 and the second switch 230 are connected in series.
the connecting piece 250 can deactivate the test circuit during mechanical opening of the breaking compartments and / or by the differential protection compartment during a differential fault.
the connecting piece 250 can be mounted inside the differential protection compartment and can make it possible to mechanically connect the at least one compartment (s) between them by at least one lateral lug 251, 251 ', preferably two lateral lugs 251, 251 '.
the connecting piece 250 may protrude from both sides of the differential protection compartment and may enter the switching compartments located, if any, on both sides of the differential protection compartment.
the connecting piece 250 can be adapted to allow the establishment of good contact of the test circuit in the differential compartment, that is to say to close the test circuit (second switch 220 closed, ability to perform the function test).
the connecting piece 250 physically opens the test circuit (second open switch and thus protects it from a short circuit in case of prolonged support and closure of the test button 222 contact).
the test button 222 when pressing the test button 222, the first switch 220 of the test button 222 is closed but as the second switch 230 is open, the test function is disabled.
the second switch 230 may comprise a first contact element 231 and a second contact element 232.
the first contact element 231 can be moved away from the second contact element 232 to open the second switch 230.
the connection piece 250 can move aside the first contact element 231 of the second contact element 232 bearing against the first contact element 231.
the first contact element 231 can be rotatably mounted in a housing 211 of the differential circuit breaker 210.
the connecting piece can deactivate the test circuit during mechanical opening of the breaking compartments and / or by the differential protection compartment during a differential fault.
