| 摘要 |
The present invention relates to a device for cutting off an electrical line, comprising a control device which includes: control shaft (310) mounted pivoting about a spindle (312) and able to move at least one moving contact (210), crankshaft (330) linked to the control shaft (310), tension lever (340) mounted so as to rotate about a spindle parallel to the spindle (312) of the control shaft (310), a tension quadrant (350) mounted so as to rotate about a spindle parallel to the spindle (312) of the shaft (310) and which interacts with the lever (340) via drive means allowing a relative range of movement between the tension lever (340) and the tension quadrant (350) upon crossing a neutral point, a control cam (360) suitable for driving the quadrant (350), and a spring (380) fixed, on the one hand, onto the lever (340), and, on the other hand, onto the crankshaft (330). <IMAGE>
