<p>A circuit interrupter (2) includes an indicator apparatus (4) having a pair of movable elements (16, 20) and a connection apparatus (24) that enables the pair of movable elements to be cooperable. One of the movable elements is connected with an indicator element (28) that indicates an OPEN and/or a CLOSED condition of the circuit interrupter. A pair of engagement structures (48, 88) are situated on the pair of movable elements and enable the pair of movable elements to be engageable with one another. A biasing element (90) 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.</p> |
