| 摘要 | PURPOSE: To prevent the erroneous operation of a circuit breaker regardless of the arrangement direction by adding a required bias force to the reset lever of an operating level latched to separate contacts in over current state in an actuator-accessory combination unit attachable to and detachable from the recessed part of a cover. CONSTITUTION: The trip. actuator latch 36 of an actuator-accessory combination unit 29 attachable to and detachable from the recessed part of the cover of a wiring circuit breaker is electromagnetically rotated to separate contacts in over current state, and a reset lever 43 and the latch 36 are latched by the latch pin 61 of a rotating latch support arm 61. To the lever 43, a bias force is added in the direction opposite to the trip spring 90 of a lever 60 by a reset spring 47 to prevent the latch 36 from being moved so as to separate from the pin 61 is trip state. Thus, an actuator-accessory combination unit capable of preventing the occurrence of a erroneous operation of a circuit breaker regardless of the arrangement direction can be provided.
