Abstract A miniature circuit breaker comprises a housing having a bimetallic element forming a movable contact and connected to one terminal of the circuit breaker and a fixed contact juxtaposed with the movable contact. A slide carries a conductive...
Abstract The separation partition (44) of the arc formation chamber (38) from the mechanism of a miniature circuit breaker is formed so as to follow at least on a part of its length some equipotential lines generated between the separated contacts (2...
Abstract A miniature circuit-breaker includes at least one thermal trip element, which includes a force translator which causes switching contacts to open. The force translator may be a breaker mechanism. The thermal trip element works with a thermal...
Abstract An improved miniature circuit breaker is provided which is adapted to improved automatic assembly of all components thereof. Key components of the breaker are individually and collectively designed to be susceptible to total Z-axis assembly....

Abstract A circuit breaker system with a shunt trip device is taught in which the shunt trip device occupies a miniature circuit breaker case and utilizes features of the miniature circuit breaker case except that it is provided with a coil and two-p...
Abstract Miniature circuit breaker apparatus is taught which includes side-by-side ganged cases where one of the ganged cases includes the main circuit breaker operating mechanism and contacts and where the other case includes an actuable micro-switc...
Abstract A miniature circuit breaker includes an elastic contact piece to contact with two terminals of a circuit, thereby electrically connecting the circuit. One end of the elastic contact piece fixed to a terminal is a fixed end, and the other end...
Abstract A miniature circuit breaker is disclosed with a latch for continuously opening and closing a contact point with a contact lever on which the moving contact member is molded. A toggle lever gear with a link connected to a switching handle and...
Abstract A miniature circuit breaker has a housing formed of a housing base of insulating material and a pot-like housing cover, which is or can be positioned onto the housing base. Two elongate and flat contact arms are partially embedded in the hou...
