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： A contact device including a fixed contact member having a fixed contact; and a movable contact member which includes a movable contact and is movable between a position where the movable contact is in contact with the fixed contact and a position where the movable contact is away from the fixed contact, a first contact member which is one of the fixed contact member and the movable contact member further including a recess in a surface to which a first contact of the first contact member is provided. The first contact protrudes toward a second contact of a second contact member which is another of the fixed contact member and the movable contact member, and a periphery of the recess at least partially surrounding a periphery of the first contact in a surface perpendicular to a protruding direction of the first contact.

摘要： The fixed contact member includes a fixed contact. The movable contact member includes a movable contact and is movable between a position where the movable contact is in contact with the fixed contact and a position where the movable contact is away from the fixed contact. The permanent magnet forms a magnetic field around the fixed contact. The case is for accommodating at least the fixed contact member and the movable contact member. Further, the case includes an accommodation part which is partitioned from an internal space of the case and is for accommodating the permanent magnet through an opening thereof directed to an outside of the case.

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： The contact device includes: a fixed contact member including a fixed contact; and a movable contact member including a movable contact. The movable contact member is movable between a position where the movable contact is in contact with the fixed contact and a position where the movable contact is away from the fixed contact. The movable contact member further includes a protrusion which protrudes from a face to which the movable contact is provided, in a direction same as a protruding direction of the movable contact.

摘要： The contact device includes an armature, a driver, a fixed contact, a movable contact, a contact spring, and a card. The driver drives the armature. The movable contact is to be in contact with and separate from the fixed contact. The contact spring is for holding the movable contact so as to allow the movable contact to be in contact with and separate from the fixed contact. The card interconnects the armature and the contact spring. The card is made of resilient material and fixed to each of the armature and the contact spring.

摘要： The contact device includes an armature, a driver, a fixed contact, a movable contact, a contact spring, a card, a case, and a positioning member. The driver is for driving the armature. The movable contact is to be in contact with and separate from the fixed contact. The contact spring is for holding the movable contact so as to allow movement of the movable contact. The card interconnects the armature and the contact spring. The case is a synthetic resin molded product. The positioning member is provided as a separate part from the case. The positioning member is for determining a positional relationship between the armature, the driver, the fixed contact, the movable contact, the contact spring, and the card, and is accommodated in the case.

摘要： A control system is designed to control an interrupter. The interrupter is started by a startup current to interrupt a main electric circuit. The startup current flows through an auxiliary electric circuit and has a current valve equal to or greater than a predetermined value. The control system includes a driving unit and a driven unit. The driving unit includes an intermediate electrical path to be connected to the main electric circuit. The driven unit is to be connected to the auxiliary electric circuit. When an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, the driving unit uses, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path. The driven unit supplies the auxiliary electric circuit with the startup current by being driven by the driving unit.

摘要： An interrupter includes a gas producer, an actuator pin, and an electrical conductor. The electrical conductor includes a first terminal portion, a first separable portion, a second terminal portion, and a second separable portion. The second separable portion is electrically connected to the first separable portion in parallel. A first timing when the first separable portion starts to be cut off from the first terminal portion is earlier than a second timing when the second separable portion starts to be cut off from the second terminal portion.
