Remote actuating device for circuit breaker, has assistance device including connection device with lever whose head has shape complementary to orifices' shapes, where head shape is interfaced with latter shapes to induce breaking

摘要

The device has a circuit breaker triggering assistance device including rotary units (3, 4) rotatably integrated to a rotative control handle (M) of a circuit-breaker (D) and a remote control unit, respectively. A helical pull-off spring (8) stresses the unit (4) towards its position. A breakable mechanical connection device has a pivoting lever (5) with a hook shaped head (51) whose shape is complementary to shapes of orifices of the units, where the head shape is interfaced with the shapes of the orifices to induce breaking of mechanical connection of the connection device.
