    Abstract: A ground fault trip unit of the three-pole type, comprises a fourth conductor passing through the differential transformer. The fourth conductor is connected to terminals located on a different face from that of the terminals of the other three conductors. The same ground fault trip unit can be associated with a three-pole breaking device, in which case the fourth conductor is not used, and with a four-pole device whose fourth pole is connected to the fourth conductor of the ground fault trip unit.

    Abstract: By articulating the neutral-pole switching element in a multi-pole circuit breaker, providing spring biasing to urge the two elements into a pre-determined position approximating alignment, advancing the neutral pole switching element with respect to the other switching elements and providing fixed contact elements which frictionally engage opposite sides of the neutral-pole switching contact in the closed position, the closing of the neutral circuit precedes the closing of the live circuits and the opening of the neutral circuit lags the opening of the live circuits, thus preventing arcing and transient damage to loads on the circuit.

    Abstract: Circuit-breaker system having a response time to shortcircuits of less than 4 milliseconds have multiple coordinated pole units wired in series in each phase. The system is able to clear a fault where the available current is high, for example 100,000 amperes at 240 volts AC although each pole unit may be of conventional construction having a current-interruption rating of only 5 or 10 thousand amperes. The operation exhibits current limiting properties, and the interruption process leaves the pole units remarkably free of arc damage.

    Abstract: PROBLEM TO BE SOLVED: To provide a power transmission device of a quadrupole circuit breaker, in which a contact of a neutral electrode is in contact earlier than a contact of other electrodes when power is on and is lately separated when power is off. SOLUTION: The power transmission device of the quadrupole circuit breaker includes: an opening/closing shaft 12 which gives drive force for opening and closing to a quadrupole movable contact 17; arms 13a, 13b, 13c, 13d which are connected to the opening/closing shaft 12, can rotate together, are arranged corresponding to the quadrupole, and transmit rotation force of the opening/closing shaft 12; and a link (typically 14b, 14d) which is connected between the arms 13a, 13b, 13c, 13d and the movable contact 17, transmits the rotation force of the arms 13a, 13b, 13c, 13d to the movable contact 17 as opening/closing drive force, and is arranged by corresponding to the quadrupole. A total length of the arm 13d of the neutral electrode and the link 14d is longer than a total length of the arms 13a, 13b, 13c of electrodes except for the neutral electrode and the link (typically 14b).
