Title:
MAGNETIC TRIPPING DISPLAY DEVICE AND CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2013/132598
Kind Code:
A1
Abstract:
This magnetic tripping display device is provided with: a housing that has a display window (22); an actuator (1) that bends in the longitudinal direction with a spring affixing part (16) provided in the vicinity of one end in the longitudinal direction and is pivotally supported in the housing at a bending part; a spring (4) that is accommodated in the actuator (1), one end of which is affixed to the housing and the other end to the actuator (1), and which applies force to the actuator (1). In a normal state, force is applied by the spring (4) to the actuator (1) such that the other end of the actuator (1) is in an initial state in which the same cannot be seen from the outside of the housing through a display window (22). When the circuit breaker carries out a tripping operation by an electromagnet part, the other end of the actuator (1) moves to and operated state in which the same can be seen from the outside of the housing through the display window (22) by the transmission of movement of the electromagnetic part.
