摘要： An electrical circuit includes a contact with a pair of switchable electrodes, the contact configured to cycle through make and break transitions while conducting current. The electrical circuit further includes an arc suppressor, at least one sensor, and a controller circuit. The arc suppressor is coupled across the pair of switchable electrodes and is to extinguish an arc formed across the pair of switchable electrodes during the make and break transitions of the contact. The at least one sensor is coupled to the pair of switchable electrodes and is configured to generate sensor data. The controller circuit includes a plurality of registers and is configured to detect a fault condition associated with the contact based on the sensor data. The controller circuit further sequences contact opening of the contact based on the detected fault condition and a timing value stored in at least one register of the plurality of registers.

摘要： The emergency stop switch unit 2 as an operation switch unit includes a direct operation part 20A and an alternative operation part 20B. The direct operation part 20A has an emergency stop button 21 adapted to be directly operated. The alternative operation part 20B is adapted to be linked with the direct operation part 20A and alternatively operates the emergency stop button 21 in place of the direct operation part 20A. The alternative operation part 20B has a reception part 32 that detects a remote operation of the emergency stop button 21 and an electromagnetic solenoid 3 that actuates the emergency stop button 21 on the basis of the remote operation detected by the reception part 32.

摘要： A system includes a dry contact with a first pair of switchable electrodes, a wet contact with a second pair of switchable electrodes, an arc suppressor, and a controller circuit operatively coupled to the arc suppressor and the first and second pairs of switchable electrodes. The controller circuit is configured to detect a failure of the wet contact and determine a stick duration associated with the first pair of switchable electrodes. The stick duration is based on a duration between an instance when a coil of the dry contact is deactivated and an instance of separation of the first pair of switchable electrodes during deactivation of the coil. The controller circuit generates, in-situ and in real-time, health assessment for the first pair of switchable electrodes based on a comparison of the determined stick duration with an average stick duration associated with a window of observation.

摘要： An electrical switch including a frame, an operating shaft, and a bridge member movable in a depth direction relative to the frame by rotation of the operating shaft, wherein the depth direction is parallel with a rotation axis of the operating shaft, and wherein the operating shaft is adapted to exert a first opening force to the bridge member during an opening event. The electrical switch includes an anti-tilting member movable in a lateral direction relative to the frame by rotation of the operating shaft, the lateral direction being perpendicular to the depth direction, wherein the anti-tilting member is adapted to exert a second opening force to the bridge member during the opening event, the second opening force being parallel to the first opening force and spaced apart from it in the lateral direction.

摘要： A switching device including a frame, a first fixed contact member having a first contact area, and a first movable contact member having a first contact arm provided with a contact area. The first movable contact member is adapted to pivot relative to the frame around a first pivoting axis between a first position and a second position. The switching device includes a spreader member that is adapted to provide a first intermediate position for the first movable contact member in which a projection of the contact area of the first contact arm overlaps at least partially with a projection of the first contact area on a switch plane perpendicular to the first pivoting axis while the contact area of the first contact arm is spaced apart from the first contact area.

摘要： At the time of contact between the contacts, the first movable contact comes into contact with the first fixed contact before contact between the second movable contact and the second fixed contact is made. The first movable contact is located on a leading end side of the contact piece with respect to the second movable contact. The first divided piece includes a body and a projection. The body extends in the lengthwise direction. The projection projects in the widthwise direction of the first divided piece from the body. The projection includes a contact portion pressed by the link member.

摘要： A breaker mechanism for an electrical circuit breaker is disclosed, the breaker mechanism including a spring, a latching mechanism and an actuating element, with which a breaker shaft of the electrical circuit breaker is actuated for breaking (OFF position) or making (ON position) the electric current. In an embodiment, the actuating element is actuated in the direction of the ON position when making the electric current, and the spring is thereby tensioned. Further, the latching mechanism releases the energy of the spring for actuating the breaker shaft of the electrical circuit breaker when the ON position is reached.
