    摘要: A solenoid type magnetic trip assembly (22) for a molded case circuit breaker (10) includes an armature (80) biased against an adjustable stop (138) by a tension spring (116) to set the initial gap (220) for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap (220). The armature (80) includes an elongated magnetically permeable member (82) mounted by a frame (84) to slide longitudinally along a pair of guide rails (122). The frame (84) defines a trip surface (104) axially aligned with the elongated magnetically permeable member (82) which engages a trip arm (160) on a trip bar (24) to trip the circuit breaker (10) in response to a predetermined level of overcurrent. A bimetal (168) providing a thermal trip function is cantilevered from a support spaced from the trip bar (24) by the armature (80), but has a terminal portion (174) at the free end (172) projecting toward the trip bar (24) and through which the elongated magnetically permeable member (82) of the armature (80) extends. A radially enlarged slug (88) on the free end of the elongated magnetically permeable member (82) of the armature (80) is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature (80) into the solenoid coil (74). This opposing force increases as the initial gap (220) increases, placing the slug (88) closer to the magnetic frame (78), so that a greater range of trip currents can be selected despite limited room for armature travel. A gap (228) in the magnetic frame (78) prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield (198) protects the bimetal (168) from deformation during high current short circuits.

    摘要: Trip device of the suction or pull-in armature type, having a yoke (18; 35) supporting a fixed permanent magnet (22) and a movable elongated armature (23) having a head member (25). The armature (23) and the yoke (18; 35) forming a first magnetic circuit for holding the armature (23) in a first position with the permanent magnet (22), in which first position the head member (25) protrudes outside the yoke (18; 35). For moving the armature (23) electromag­netically and/or electrothermally to a second position in which the head member (25) protrudes further outside the yoke (18; 35), the yoke (18; 35) is provided with electrothermal bimetal means (33; 37). For moving the armature (23) to the second position independently of the polarity of an electrical current, a second magnetic circuit is provided, consisting of a further yoke and one or more magnet windings (30), or consisting of a pair of mutually magnetically separate branches (44, 45; 50, 51) magnetically con­nected in series with the first magnetic circuit, and one or more magnet windings (46) for mutually oppositely magnetizing the branches (44, 45; 50, 51).

    摘要: An improved miniature circuit breaker (1, 2) 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. In particular, the trip mechanism (6) including the trip lever (31), and the associated activation means (75), tension means (43) and reset means (35) are defined by elements designed to interact in a Z-axis assemblable fashion. The trip mechanism components (6) are also designed for improved trip action and enhanced breaker performance in repeated CLOSED, and TRIP operations.
