Document Type and Number:
Japanese Patent JP5192555
Kind Code:
B2
Abstract:
Provided herein is a power transmission mechanism for a four poles circuit breaker in which the contacts of a neutral pole thereof are brought into contact earlier at the time of closing and separated later at the time of opening than those of the other poles thereof, and according to the present invention, there is disclosed a power transmission mechanism for a four poles circuit breaker comprising: a switching shaft (12) configured to provide a driving force for switching to the movable contactors of the poles; an arm (13a, 13b, 13c, 13d) provided to correspond to the four poles to transfer the rotational torque of the switching shaft; and a link (14b, 14d) configured to transfer the rotational torque of the arm to the movable contactor as a switching force, and provided to correspond to the four poles, wherein the sum of the length of the arm and the link in a neutral pole is longer than the sum of the length of the arm and the link in the poles excluding the neutral pole.
