Abstract: 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.

Abstract: This cutoff device includes: an electrical path; a first coil in which a first induced current corresponding to an electric current flowing through the electrical path is generated; a breaker that interrupts the electrical path; and wiring that electrically connects the first coil and the breaker. The breaker is driven with the first induced current generated in the first coil.

Abstract: An electromagnetic relay includes an electromagnet device, a contact device, and a trip device. The electromagnet device includes a first stator, a movable element, and a first exciting coil. The contact device includes a movable contact and a fixed contact. A trip device includes a second exciting coil. The electromagnet device moves the movable element from a first position to a second position. The trip device moves the movable element to a third position. An open state is reached when the movable element is in the first position and the third position. A closed state is reached when the movable element is in the movable element is in the second position.
