摘要： A circuit breaker includes a housing, an operating mechanism, and a cassette. The cassette includes a separable current path having a movable contact arm, two arc receptors each disposed for receiving an electrical arc in response to a short circuit overcurrent condition, and two slot motors each disposed proximate the movable contact arm for magnetically driving the movable contact arm to a blown open position in response to a short circuit overcurrent condition. The slot motors each have two side legs opposing each other and defining a space therebetween for receiving the movable contact arm, each side leg having a magnetic core and an insulative layer and being biased toward the interior of the side walls of the cassette, wherein each side leg is restrained from being magnetically attracted toward the movable contact arm during a short circuit condition.

摘要： A circuit breaker includes a movable contact, a fixed contact, a switching device, a switching operation handle, and an over-current tripping device. The switching device has a switching lever connected to the handle, a toggle linkage having an upper link and a lower link for connecting to the movable contact, a tripping mechanism for activating the toggle linkage in response to over-current, and an operation spring tightly stretched between the switching lever and the toggle linkage. A locking member is provided in the switching device for interconnecting the toggle linkage and the switching lever and for restricting a movement range of the switching lever according to an operational position of the toggle linkage. When main-circuit contact points are stuck, the locking member restricts the movement of the switching lever and prevents the handle from moving to the OFF position.

摘要： A circuit breaker includes a housing; separable contacts mounted in the housing; and an operating mechanism for opening and closing the separable contacts. An overcurrent assembly is responsive to selected conditions of current flowing through the separable contacts and actuates the operating mechanism to trip open the separable contacts. A bonnet forms a U-shape which surrounds the separable contacts and which cools and splits an arc when the operating mechanism trips open the separable contacts. A first bonnet piece forms a first leg of the bonnet, and a second bonnet piece forms a second leg and a base of the bonnet.

摘要： A multipolar circuit breaker of great breaking capacity prevents arc gas from blowing out from the side at the time of cutting off a short-circuit current. A stationary contact and a movable contact generating arcs when a short-circuit current is cut off, and an arc extinguisher extinguishing the arc are stored in an arc extinguisher casing. By forming the ceiling, the bottom and the sidewalls connecting the ceiling and the bottom of the arc extinguisher casing in continuity so that no gap is formed by an outward internal pressure, blow out of arc gas from the sidewall portion is suppressed.

摘要： The aim of the invention is to protect an electromagnetic switching device when a load (6) is switched to a supply voltage (U). A current (IL) that flows through the load contact (2) is monitored. The electric circuit is interrupted when the current (IL) exceeds a threshold value that is below the current carrying capacity of the load contact (2). The electric circuit is automatically closed again after the current (IL) which flows through the load contact (2) has decreased.

摘要： The invention concerns a switching appliance comprising several main dual cut-out poles provided with fixed contacts housed in an arc box and mobile contacts located on a mobile contact-holder (30). The latter is equipped, for the main contacts, with main housings (31) aligned transversely to the direction (X) of displacement of the contact-holder (30), and, for the auxiliary contacts, secondary housings (32) aligned transversely to the direction (X) and located in front of the main housings (31). The contact-holder comprises between the main housings and the secondary housings a vertical insulating wall (35). The arc box consists of two half boxes (20, 40) assembled in a horizontal plane, so that one of the two halves provides guiding elements and stop elements for the contact-holder (30).
