Abstract
PURPOSE: To raise the reliablity of operation, by providing a longitudinal hole in a frame integrated with a yoke of an overcurrent element and controlling the motion of a support shaft of a moving contactor and making the motion of the moving contactor accurate.
CONSTITUTION: The overcurrent protective relay comprises a tripping plate 3 which is operated by an armature 2 responsible to the overcurrent element 1, and the moving contactor 6 which is latched with the tripping plate 3 and has contact 4 at one end and is normally kept closed by a spring 5 but is unlatched and opened in response to an overcurrent. The frame 11 integrated with the yoke 10 of the element 1 is provided with the longitudinal hole 16 for controlling the motion of the support shaft 17 of the moving contactor 6 and with the armature 2 and a shaft of the tripping plate 3. Thereby, the relative position accuracy between the overcurrent element and the armature, the tripping plate and the moving contactor is improved. Thus, the movement of the armature, the tripping plate and the moving contactor is made accurate and sure.
