摘要： A thermal overload open-phase tripping device includes in a case bimetals corresponding to different phases; a differential shifter mechanism composed of a push shifter and a pull shifter, linked to operating ends of the bimetals, and an interlocking plate; and a compensating bimetal for transmitting output from the shifter mechanism to an opening and closing mechanism section of a breaker main body. The push and pull shifters are slidably supported to extend over interphase partition walls in the case, and a case cover is placed and held over the push and pull shifters. Rib-shaped projections projecting from an inner surface of the case cover and facing the top surfaces of the shifters are provided as shifter position guides to constrain inclination of the shifters moving in accordance with bending displacement of the bimetals to hold the shifters horizontally.

摘要： The invention relates to a low voltage switchgear with a bimetallic actuator, especially to a motor safety switch. The aim of the invention is to improve such a low voltage switchgear so that the fabrication and assembly tolerances are widely compensated for. To this end, the two-part (21, 22) housing (2) of the switchgear (1) is provided with an opening (23), that is closed with a protective cover (24). By way of said opening (23), the bimetallic component (51) and the jack system are accessible for the purpose of measurement and a bridge system (52) of the bimetallic actuator (5) that is calibrated on the basis of the measured values can be mounted therethrough.

摘要： A two-pole miniature circuit breaker is configured for calibration of both pole mechanisms with the circuit breaker fully assembled. The identical pole mechanisms are mounted in the same orientation in parallel outer compartments of a molded housing with the metal support frame of one pole against the outer housing wall and the frame of the other spaced from the associated outer wall. A coupler couples the two-pole mechanisms together for simultaneous opening of both poles when either pole is tripped has an actuating member on each end which engages the trip device of the associated pole. The actuating member, at least of the pole with the metal frame spaced from the housing outer wall, is configured to provide direct access for a calibration tool inserted through a calibration opening in the housing to engage a calibration slot in the metal frame.
