<p>A movable contactor assembly for a current limiting type MCCB comprising: a terminal base (180) fixedly installed on a case of the MCCB; a plurality of movable contactors (110) having a cam face portion; a pair of holder plates (120) supporting the movable contactors at both sides thereof; a plurality of first springs (140) providing an elastic force to the movable contactors (100) in a direction in which the movable contactors (110) are brought into contact with the fixed contactors (1) when the MCCB is in a closed circuit state, and providing an elastic force to the movable contactors (110) in a direction in which the movable contactors (110) are separated from the fixed contactor (1) when the MCCB performs a current limiting operation; a plurality of extending plate portions (181,183,185) provided to face the side of one end portion of each of the movable contactors (110) so as to be electrically connected with the movable contactors (110); a plurality of flexible wire plates (170) electrically connecting the movable contactors (110) and the terminal base (180) and having a portion bendable toward the movable contactors (110) or toward the extending plate portions (181,183,185); and a second spring (PS1,PS2) providing an elastic force to the flexible wire plates (170) so as to be tightly attached to the movable contactor (110).</p> |
