摘要： A terminal unit having connection conductors to be connected to corresponding terminals of a switch is installed in a terminal section of the switch, and an external electric wire is connected to each terminal section of the connection conductors. Thus, the insulation distance between phases for the terminal sections and the insulation distance between the terminal section and a panel cut surface are increased according to the requirement of the switch. The shape and size of the terminal unit can be set regardless of the switch, so that a required insulation distance is obtained without increasing the size of the switch main body.

摘要： In a terminal structure of a switch which is arranged in a manner that a terminal conductor 14 with a terminal screw drawn from the inner portion of the casing is disposed at every phase in the terminal portion of a casing formed by the three-divided structure of an upper cover 2, an intermediate cover 3 and a lower cover, and wires inserted into the terminal portion from the outside are respectively fastened by the screws to be coupled to the terminal conductors, the terminal conductors of the respective phases are pressed into the terminal fixing grooves 3b formed at the intermediate cover and fixed to the casing in a manner that the left and right side edges of each of the terminal conductors are pressed into the grooves. The terminal conductor of each phase is surrounded by a side wall 2a and an inter-phase partition wall 2b formed at the upper cover, and the fitting portion of the upper cover and the intermediate cover is defined at a portion lower than the terminal conductors thereby to enlarge the width of a space into which wires are inserted. Further, step portions 3b-1 are formed at portions of the terminal fixing grooves so that two kinds of terminal conductors having different plate thickness can be selectively assembled in the intermediate cover.

摘要： In a make-and-break mechanism for use in a circuit breaker, an alarm output plate 56, which is disposed so as to be slidable in the vertical direction along the frame (cover plate) 27 of the make-and-break mechanism, is secured to the engaging projection 27d of the cover plate 27 through a pair of right and left guide holes 57 formed therein. At the same time, one end of a handle spring 59, which, in the trip operation, is used to rotate an operation handle 26 to a trip display position, is caught on the alarm output plate 56. In case where a latch receiver 47 is driven or rotated by the overcurrent detect portion of the make-and-break mechanism and the secured condition of a latch is thereby removed, the electric circuit of the circuit breaker is broken due to the stored energy of a main spring 64 and, in this case, the alarm output plate 56 is driven or slided in the lateral direction and thus the secured condition of the alarm output plate 56 is removed, so that the alarm output plate 56 is driven in the upward direction due to the spring force of the handle spring 59 to thereby operate an alarm contact.

摘要： A circuit breaker with overload and short-circuit protection functions for a motor, on which is mounted a thermally actuated overload tripping device including an adjustment dial to set a value corresponding to a rated current value of the motor on a scale. The dial has a standard setting pointer mark and a correction setting pointer mark side-by-side along a perimeter. The standard setting pointer mark applies to using the circuit breaker as a single item. The correction setting pointer mark applies to using a number of circuit breakers arranged in a line in close contact with each other. By setting a mark selected according to the arrangement of the circuit breaker at the rated current value, the steady state current value of the tripping device can be adequately set to correspond to the rated current value of the motor.
