Zusammenfassung: | To realize cost reduction and size reduction by reducing the number of components used for switching a contact mechanism.SOLUTION: An electronic overload relay includes a contact mechanism that can be switched between a steady state and a trip state, an electromagnet having a movable shaft that moves in the axial direction when energized, a slider that moves in the axial direction in conjunction with the movable shaft when energized, and a driven member that alternately switches the stop position of the slider after movement in the axial direction between a first stop position corresponding to the steady state and a second stop position corresponding to the trip state each time the electromagnet is energized.SELECTED DRAWING: Figure 4
【課題】接点機構の切り替えに使用する部品点数を少なくすることで、低コスト化および小型化を実現できるようにすること。【解決手段】電子式過負荷リレーは、定常状態とトリップ状態とに切り替え可能な接点機構と、通電時に軸方向に移動する可動軸を有する電磁石と、前記通電時に前記可動軸と連動して前記軸方向に移動するスライダと、前記電磁石が通電される毎に、前記スライダの前記軸方向への移動後の停止位置を、前記定常状態に対応する第1の停止位置と、前記トリップ状態に対応する第2の停止位置とに交互に切り替える従動部材とを備える。【選択図】図4 |
