摘要： A circuit interrupter includes a fixed terminal, a movable contactor, a moving mechanism, a squib, and accommodation. The fixed terminal includes a fixed contact. The movable contactor includes a movable contact connected to the fixed contact. The moving mechanism is configured to move the movable contactor from a closed position where the movable contact is connected to the fixed contact to an open position where the movable contact is separated from the fixed contact. The squib is configured to generate gas by combustion. The accommodation is for accommodating the fixed contact and the movable contactor. In the circuit interrupter, the gas is introduced into the accommodation.

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： A circuit interrupter includes: a first fixed terminal including a first fixed contact; a movable contactor which is formed as a separate part from the first fixed terminal and includes a first movable contact; a holding unit configured to hold the movable contactor so that the first movable contact is connected to the first fixed contact; and a squib configured to generate gas by combustion. In the circuit interrupter, pressure of the gas generated by the squib causes movement of the movable contactor in a direction away from the first fixed terminal so that the first movable contact is separated from the first fixed contact.

摘要： A first conductive member is fixed to a first fixed terminal having a longitudinal direction, and a second conductive member is fixed to a second fixed terminal having a longitudinal direction. The first fixed terminal and the second fixed terminal are fixed to a partition member. A first extension portion of the first conductive member includes a first opposed portion opposed to at least one of the first fixed terminal at a first fixed contact side of the partition member. The first opposed portion extends in the longitudinal direction of the first fixed terminal.

摘要： The contact apparatus includes a fixed contact, a movable contact, and an arc extinguishing member. The movable contact is movable between a closed position where the movable contact is in contact with the fixed contact and an open position where the movable contact is separate from the fixed contact. The arc extinguishing member is for discharging an arc extinguishing gas offering a capacity for extinguishment of an arc, into a space containing the fixed contact and the movable contact.

摘要： 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.
