摘要： A fault interrupter and load break switch includes a trip assembly configured to automatically open a transformer circuit electrically coupled to stationary contacts of the switch upon the occurrence of a fault condition. The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.

摘要： A current limiting power switch has a monolithic stationary conductor with a conductor section that mounts fixed contacts that engage moving contacts on moving contact fingers to form a reverse current loop with the contacts closed. A terminal section projects transversely from one end of the conductor section and an arc runner section extends from the other end. The tapered arc runner has a generally laterally centered tapered area that gathers the arcs and urges them along a raised rib on the arc runner to an arc chute. A reinforcing rib running from the back of the conductor and arc runner sections to the terminal section resists distortion of the monolithic stationary conductor by the high temperatures and closing and electromagnetic forces during interruption.

摘要： A circuit interrupter provides a conducting path between two conductors and interrupts the conducting path in response to overcurrent conditions in the conductors. The interrupter includes a magnetic core around which the conductors are disposed. Each conductor is electrically coupled to an arc runner and a spanner is biased into contact with the arc runners to compete a conducting path between the conductors. A secondary response mechanism is provided adjacent to the core and includes arms extending around the core and a magnetic body. In response to overcurrent conditions of a first magnitude the body of the secondary response mechanism is attracted to the core causing the arms to displace the spanner out of contact with the arc runners. In response to overcurrent conditions of a second magnitude, such as due to direct short circuits, the spanner is repelled rapidly to a non-conducting position and the secondary response mechanism is attracted to the core to hold the spanner in the non-conducting position. The core shapes an electromagnetic field due to current in the conductors and the field causes extremely rapid expansion of arcs generated during movement of the spanner, resulting in very fast extinction of the arcs and a very brief turnoff time.

摘要： A pair of main contacts and a pair of arcing contacts are electrically and mechanically interconnected within a current limiting circuit interrupter. A common operator biases the main contacts in a closed contact condition, while simultaneously biasing the arcing contacts to an open condition. A contact driver operating to open the main contacts simultaneously closes the arcing contacts causing circuit current to pass through both the main and arcing contacts. Further displacement of the moving contacts completely directs the circuit current through the arcing contacts for electromagnetic repulsion and arcing within a magnetic structure.

摘要： A low inductance resistor for high current limitation is arranged from a single conductor wrapped in a continuous direction to form a plurality of turns wherein current transport through each of the turns induces a corresponding magnetic field to oppose the magnetic field induced within each next adjacent turn. The resistor finds application within a current limiter unit which employs magnetic repulsion and gas pressure to direct arcs that occur between separating contacts to within the high voltage region of an arc chute. The resistor is connected across the arc to reduce the arc current to a low enough value so that the arc becomes extinguished within a predetermined period of time.

摘要： High speed trip facility is provided within a molded case circuit breaker used within industrial applications. The movable contact arm is pivotally arranged to open independently of the trip unit-driven operating mechanism. A "latch kicker" arrangement interfaces between the mechanism trip bar and the circuit breaker intermediate latch whereby rotation of the trip bar causes the latch kicker to immediately displace the intermediate latch from the circuit breaker cradle thereby allowing the interrupter mechanism to untoggle the mechanism and open the breaker contacts.

摘要： Current limiting stationary (2) and movable (6) contacts are arranged to provide spaced, parallel oppositely directed current paths therein whereby fault currents generate electromagnetic forces for repelling the movable contact (6) from the stationary contact (2). An electrically resistive arc runner (20) has an arc transfer segment (20a) disposed along the path of movement of the movable contact (6) and is biased at one end (20b) into current carrying engagement with a stop (22) on stationary contact (2). The other end of the transfer segment (20a) is connected through a major length of the arc runner (20) to the stationary contact (2) at a point distinct from stop (22). An arc drawn between the contacts (2, 6) at separation initially passes current to the transfer segment (20a) and the stationary contact (2) through stop (22). Gas pressure from the arc subsequently forces a separation of the arc runner end (20b) from the stop (22) whereby current is directed through the major length of the arc runner to the stationary contact for increasing the resistance of the arc for extinguishing the arc.

摘要： A current limiter unit employs both a magnetic repulsion field and a gas pressure force to direct arcs to within the high voltage region of an arc chute. The unit confines the evolved gas pressure in all directions except in the direction of the arc plates. Venting the opposite end of the arc chute rapidly motivates the arc through the arc plates and out of the unit. Venting the sides of the arc chute reduces the back pressure produced by arc gases as well as the pressure exerted upon the heated breaker casing. The combination of magnetic and directed gas repulsion substantilly reduces the I.sup.2 t value of the unit. A parallel positive temperature coefficient impedance can be connected across the arc to reduce the arc current to a low enough value so that the arc becomes extinguished within a predetermined period of time.

摘要： An electromagnetically operated electric switch combines the function of a contactor and a current-limiting circuit-breaker. The contact assembly of the switch includes two contact systems, which are different in function, with a fixed contact which is common to both systems. The first contact system is intended for normal operating current connections, whereas the other contact system is intended for breaking short-circuit currents. The contact-making elements in the two contact systems can be made of different contact materials, in order to obtain a long electrical and mechanical life.
