    摘要： A so-called no-fuse circuit breaker of a predetermined interrupting capacity is integrally combined with a current limiting circuit interrupter with contacts which are opened by electromagnetic force and having a larger interrupting capacity then the no-fuse circuit breaker. Overcurrents within the interrupting capacity of the no-fuse circuit breaker are interrupted by the same whereas overcurrents exceeding said interrupting capacity are interrupted by the current-limiting circuit interrupter before the no-fuse circuit breaker operates.

    摘要： A switch suitable for DC applications includes: two fixed conductive contacts with first contact areas; a movable conductive bridge with two second contact areas for being connected to the two first contact areas in the on-status and for being disconnected from the two the first contact areas in the off-status; and two arc-extinguishing units configured to extinguish electric arcs occurring between the first and second contact areas after disconnecting the second contact areas from the first contact areas. First conductive arc-guiding elements extend from each first contact area into the corresponding arc-extinguishing unit and at least one second conductive arc-guiding element extends into the arc-extinguishing units suitably shaped to guide the electric arcs from each of the second contact areas of the movable bridge into the arc-extinguishing units.

    摘要： A circuit interruption device includes a conductive element configured to be coupled to a circuit, a contact arm configured to move with respect to the conductive element between a first position and a second position, and a biasing element configured to apply a biasing force on the contact arm to maintain contact between the contact arm and the conductive element when the contact arm is in the first position, wherein the contact arm is configured such that a current flow through the contact arm causes an electromagnetic repulsive force to act on the contact arm in a second direction that is opposite the first direction.

    摘要： A circuit breaker having an automatic release linkage is disclosed that is capable of preventing damage and deformation of elements by automatic linkage release before electro-impulsive force generated from within the circuit breaker by a large short-circuit current causes the damage and deformation of open/close linkage.
