Abstract (en)

[origin: EP0461027A1] This is a differential release device whose release mechanism (24) is able to intervene on the release member of a main release device in the event of a differential defect. According to the invention, this release mechanism (24) includes, for this action, a main lever (44) and, coupled with the operating handle of the main release device, an operating handle (60), which is able systematically to ensure, by itself, under the stress of its return spring (63), automatic resetting of this main lever (44) before reaching its own release position. Application in particular to circuit-breakers. <IMAGE>
