摘要： The invention relates to a electric switching device with a bi-metal tripping device and a latching mechanism with a releasing jack system to be triggered by the tripping device via a tripping bridge, in particular a motor protection switch or a circuit breaker. The invention also relates to a method for compensation of different bending distances of at least two bi-metal tripping devices of in parallel operated conductor rails. The objective of the invention is to provide an electric switching device with at least two conductor rails, which are operated in parallel, a bi-metal tripping device for each conductor rail and a release jack system to be triggered by the tripping device which does not trip under normal operating states, i.e. which does not trip to early. The invention discloses an electric switching device with at least two conductor rails, which are operated in parallel, a bi-metal tripping device for each conductor rail, a first tripping bridge with jogs for the bi-metals and a releasing jack system to be triggered by the tripping device via the first tripping bridge having a second tripping bridge and a tripping lever, which is able to detect different bending distances of the at least two bi-metal tripping devices of the parallel operated conductor rails and to control the releasing jack system via the tripping lever in such a way, that the forward motion of the more bended bi-metal tripping device will be compensated. The invention also discloses a method for compensating different bending distances of such electric switching device.

摘要： A shutter (20) for insulating electrical contacts (54) includes a first panel (22) having a first opening (30) and a second panel (24) having a second opening (30). The first opening is offset from the second opening when the shutter is in a closed position. The second panel (24) includes a first guide (34) configured to react to a pressure of a phase barrier (60) of an insertable withdrawable unit (10) thereon to move the second panel in a first sliding direction relative to the first panel such that the first and second openings align so as to allow an electrical contact to extend therethrough. A spring housing (100) having a spring disposed therein between at least two support legs (102, 103) is slidably disposable in the first panel (22) and extends through the second panel (24).

摘要： The invention relates to a current measuring method for switchgear having current paths (L21; L22) connected in parallel. The digital measured values (Ι1'; Ι21'; Ι21'; I3') derived from the path currents (i1; i21; i22; i3) are converted into corrective values (I1; I2; I3) to compensate (Kn; Kp) for the non-linear transmission characteristics (N) associated with the transformer-based current transformation. The respective total value and difference values are determined from the digital measured values (I21', I22') associated with the current paths (L21, L22) connected in parallel, wherein at least one respective difference value is included in forming the associated corrective values (12) and the associated corrective values (12) represent the total of the associated path currents (i21, i22).
