摘要： A device for protecting electric circuit against electric overloading comprises a casing, in which in addition to an actuating handle (1), an engaging strap (2), an actuating lever (3), a disconnecting lever (4) and a trigger (5) two sensors (81, 82) for detecting velocity are integrated. The first sensor (81) is mounted adjacent to said actuating lever (3) and adjusted to cooperate with a protrusion (34), with which said actuating lever (3) is furnished, and to detect the velocity (Vv) of movement of the actuating lever (3). The second sensor (82) is mounted adjacent to said actuating handle (1) and adjusted to cooperate with a protrusion (12), with which said actuating handle (1) is furnished, and to detect the velocity (Vg) of the actuating handle (1) when rotated around its pivot point (10). Both sensors (81, 82) are connected with a control unit (9), which is on the other hand connected with at least two indicators (91, 92, 92), which are available on said casing and are visible from outside.
