Claim 1
Independent Claim
233 words
Automatic cut-out having an electromagnetic breaker (43) with a magnetic armature (44), a thermal breaker (41), a fixed and a movable contact piece (64, 28), a switch latch which can be released by the thermal and magnetic breaker (41, 43) and which has a latching point formed by a release lever (38) and a pawl lever (35) rotatably mounted fixed in place and having a slot (34) for guiding a shackle (33), the magnet armature exerting an opening action directly on the movable contact piece and the switch latch opening the movable contact piece permanently, with a switch handle (22) projecting from the front wall of the housing intended for the manual actuation of the switch latch, and with an intermediate lever (31) which is articulated at its one end on the contact lever (16) and at its other end on one leg of the shackle (33) and which engages into the slot (34) with this leg, the other leg of the shackle (33) being articulated on the switch handle (22), characterized in that the intermediate lever (31 ), the pawl lever (35) and the slot (34) are guided so as to extend approximately parallel to the front wall (1 OA) and parallel to the side walls of the housing (10), and in that the release lever (38) is mounted, together with the switch handle (22), on an axle (21) fixed in place.
Claim 2
Dependent Claim
233 words
Automatic cut-out having an electromagnetic breaker (43) with a magnetic armature (44), a thermal breaker (41), a fixed and a movable contact piece (64, 28), a switch latch which can be released by the thermal and magnetic breaker (41, 43) and which has a latching point formed by a release lever (38) and a pawl lever (35) rotatably mounted fixed in place and having a slot (34) for guiding a shackle (33), the magnet armature exerting an opening action directly on the movable contact piece and the switch latch opening the movable contact piece permanently, with a switch handle (22) projecting from the front wall of the housing intended for the manual actuation of the switch latch, and with an intermediate lever (31) which is articulated at its one end on the contact lever (16) and at its other end on one leg of the shackle (33) and which engages into the slot (34) with this leg, the other leg of the shackle (33) being articulated on the switch handle (22), characterized in that the intermediate lever (31 ), the pawl lever (35) and the slot (34) are guided so as to extend approximately parallel to the front wall (1 OA) and parallel to the side walls of the housing (10), and in that the release lever (38) is mounted, together with the switch handle (22), on an axle (21) fixed in place.
Claim 3
Dependent Claim
79 words
Automatic cut-out according to Claim 1, characterized in that the thermal breaker (41) and the magnet armature (44) are coupled to the release lever (38) by means of a transmission slide (39) for releasing the switch latch, this transmission slide being guided in a guide groove (40) provided in the housing approximately parallel to the front wall and serving for transmitting the movement of both the thermal breaker (41) and the magnet armature (44) to the release lever (38).
Claim 4
Dependent Claim
45 words
Automatic cut-out according to Claim 2, characterized in that formed on the magnet yoke of the magnetic breaker is a pivot bearing (50) for a two- armed lever (42) which serves for transmitting the movement of the magnet armature (44) to the transmission slide (39).
Claim 5
Dependent Claim
58 words
Automatic cut-out according to one of the preceding claims, characterized in that the contact lever (16), the switch handle (22) and the pawl lever (35) are mounted between two L-shaped plates (19), one leg of the plates (19) receiving the contact-lever axle (17) and the other leg receiving the switch-handle axle (21) and the pawl lever axle (36).
Claim 6
Dependent Claim
30 words
Automatic cut-out according to one of the preceding claims, characterized in that the magnet yoke has an extension (53), to the end of which is fastened the thermal breaker (41).
Claim 7
Dependent Claim
102 words
Automatic cut-out according to Claim 5, characterized in that the extension (53) is made Y-shaped, the thermal breaker being fastened to its web, and in that for adjustment purposes there is, between the two legs of the extension (57, 57A), an adjusting screw (56) which is guided in an internal thread on one leg (57) and which rests against the inner fase of the other leg, in such a way that it is possible to adjust the thermal breaker by varying the aperture width of the two legs and thereby varying the position of the web (55) in relation to the legs.
Claim 8
Dependent Claim
37 words
Automatic cut-out according to one of the preceding claims, characterized in that the arc guide plate (62) carrying the fixed contact piece (14) is arranged in the housing in a curve of large radius without a break.
