回路安全装置及び表示器
Document Type and Number:
Japanese Patent JP6611607
Kind Code:
B2
Abstract:
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.
