| 20080290971 | ELECTRICAL SERVICE SWITCHING DEVICE - The disclosure relates to an electrical service switching device, e.g., a circuit breaker, having a magnetic release with a magnet armature, a thermal release, a fixed and moving contact piece, a switching mechanism which can be tripped by the thermal and magnetic release and has a latching point which is formed by a tripping lever and a catch lever which is mounted in a fixed position such that it can rotate and has an elongated hole in order to guide a clip, wherein the magnet armature can act on the contact lever, to which the moving contact piece is fitted, in order to open the contact point in the event of a short, and the switching mechanism can hold the contact lever permanently in the open position, having a switching toggle for manual operation of the switching mechanism, and having an intermediate lever which is articulated at one of its ends with the contact lever and at its other end on the clip, wherein the clip is articulated with at least one limb on the switching toggle. | 11-27-2008 |
| 20100072049 | ELECTRICAL SWITCH - An electrical switch with a main current path and an auxiliary current path comprises a first stationary contact piece, a first moveable contact piece, a contact lever, a second stationary contact piece, a second moveable contact piece, a contact carrier, a toggle switch, a first intermediate lever, a control lever, a second intermediate lever, a latching lever, a release lever configured to form a latching connection with the latching lever at a latching point, and a tripping spring. | 03-25-2010 |
| 20100127816 | INSTALLATION SWITCHGEAR - An installation switching device includes a housing, a main contact point having an arc quenching chamber, an input terminal, an output terminal, an impact-style armature system configured to move the main contact point to an open position, a latching mechanism having a latching point and configured to open an isolating contact point disposed in a secondary current path parallel to a main current path, a main thermostatic bimetallic strip configured to act on the latching point to as to cause the main contact point to remain in the open position, a current limiting resistor disposed in the secondary current path, a selective thermostatic bimetallic strip disposed in the secondary current path and configured to act on the latching mechanism, a handle configured to act on the latching mechanism so as to open and close the main contact point, and a phase connecting rail. | 05-27-2010 |
| 20100133074 | LOCKING DEVICE FOR AN INSTALLATION SWITCH DEVICE - A locking apparatus for prevention of unauthorized switching-on of a service switching device includes a release lever disposed within a device housing, a switching mechanism movable from a latched state to an unlatched state by the release lever, and a release lever actuating part disposed in an area of the device housing in which the release lever is disposed. The release lever actuating part is movable from outside the switching device between a switched-on position and a switched-off position. The release lever actuating part is coupled to the release lever so as to hold the release lever in the unlatched state when the release lever actuating party is in the switched-off position. | 06-03-2010 |
| 20100133078 | INSTALLATION SWITCHING DEVICE - An installation switching device having an insulating material housing with a front face and an attachment face connected by two broad faces and an input and an output narrow face; an input terminal; an output terminal, wherein a current path runs from the input terminal to the output terminal; a switching mechanism configured to open or close a main contact point so as to switch the current path off and on, respectively, the switching mechanism having a switching handle configured to operate the switching mechanism; and at least one phase connecting rail disposed in an interior of the housing close to and parallel to the attachment face and electrically and mechanically isolated from other components and assemblies in the housing. | 06-03-2010 |
