    Abstract: A current limiter having an excellent current-limiting function and produced at low cost and a circuit breaker comprising the same and having a small impedance are provided so as to prevent the case from being damaged because of an unwanted increase of the pressure inside the case due to an arc. Contactors (1, 7) have respective contacts. When the contacts are in contact with each other, the ends on the contacts' side are in a cylindrical space in a cylindrical insulator (25); when the contacts are out of contact, one of the contacts is outside the cylindrical space. If an arc is produced, the pressure in acylindrical space (18) is abruptly increased to decrease the arc current, thus improving the current limiting performance.

    Abstract: A circuit breaker equipped with a mechanism for current limiting by the use of electromagnetic repulsion, aiming at solving a technical problem of improving current-limiting performance by increasing the contact-opening speed of a contact plate of a current-limiting type circuit breaker and realizing the device in a compact size. The current-limiting contact plate is rotatably supported at its central portion, with one end thereof facing a movable contact plate, and with the other end facing a fixed conductor and electrically connected thereto. An electromagnetic repulsive force between the movable contact plate and the current-limiting contact plate and an electromagnetic repulsive force between the fixed conductor and the current-limiting contact plate are used as a couple of forces. It is therefore possible to increase the contact-opening speed and to decrease the distance between the current-limiting contact plate and the fixed conductor. The invention provides a circuit breaker which is small in size and is excellent in breaking performance.

A slot motor structure is disposed about the contacts and a portion of the movable arm. An insulative housing at least substantially covers and insulates the slot motor structure from the movable arm and contacts. The inslulative housing includes a base and a pair of arms disposed therefrom. Each of the arms includes a first portion disposed proximate the first arc plates and a second smaller portion disposed proximate the second arc plates. A space extending from the first portion, not occupied by the second portion, is generally occupied by a portion of the second arc plates. The second portion forms a debris shield between the second arc plates and the operating mechanism.
