    摘要： A circuit interrupter includes an indicator apparatus having a pair of movable elements and a connection apparatus that enables the pair of movable elements to be cooperable. One of the movable elements is connected with an indicator element that indicates an OPEN and/or a CLOSED condition of the circuit interrupter. A pair of engagement structures are situated on the pair of movable elements and enable the pair of movable elements to be engageable with one another. A biasing element extends between the pair of movable elements and is configured to absorb some of the kinetic energy of a trip event, which resists breakage of the indicator apparatus. The indicator element changes states when the set of separable contacts are at a relatively small amount of separation and does not require the set of separable contacts to reach the end of their travel before changing state.

    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.
