摘要： An electromagnetic relay includes an electromagnet device, a contactor, and a trip device turning the contactor into an open state in which the contactor opens when an abnormal current flows. The electromagnet device includes a first excitation coil, a fixed element, first and second movable elements, and a permanent magnet. The contactor includes a fixed contact and a movable contact. In the electromagnetic relay, while the permanent magnet causes the first movable element to attractingly contact the second movable element, the fixed element attracts the first movable element due to a magnetic flux generated by the first excitation coil so as to move the second movable element together with the first movable element from a normal position to an attracted position. In the contactor, the movable contact moves, as the second movable element moves, so as to switch between a closed state in which the movable contact contacts the fixed contact and the open state in which the movable contact is removed from the fixed contact. The contactor is turned into the closed state when the second movable element is located at the attracted position. The trip device includes a second excitation coil connected in series to the contactor and a spring for acting a force on the second movable element in a direction away from the first movable element.

摘要： In a main magnetic circuit, first pulling force generated based on a first component of the magnetic flux flowing through the main magnetic path pulls a movable core in a reciprocation direction of the movable core. The first pulling force increases with a reduction of a dimension of the gap. In an auxiliary magnetic circuit, second pulling force generated based on the second component of the magnetic flux flowing through the auxiliary magnetic path pulls the movable core in the reciprocation direction of the movable core. In the auxiliary magnetic circuit, the second pulling force with the dimension of the gap being within a first range is changed to be higher than the second pulling force with the dimension of the gap being within a second range, the second range being smaller than the first range.

摘要： An electrical relay (2) includes an electromagnetic drive system for providing bi-directional drive. The electrical relay (2) includes a first a coil (212) and a second coil (213). A current is supplied to the coils (212) and (213) in opposite directions. The two coils (212) and (213) can be used to accelerate the armature in either direction in relation to the two contacts. This can be used to drive the armature to either one of the contacts and to accelerate and decelerate the armature during a single transit. In the latter regard, the armature can be accelerated and decelerated to shorten the transit time, reduce bounce, reduce wear on the contacts, and allow for different contact material options.
