CIRCUIT BREAKER

摘要

A circuit breaker (90) includes a housing (93), separable contacts (5), an operating mechanism (96) having a pivotally mounted operator handle (91) for opening and closing the separable contacts (5), and a trip mechanism (9,53) releasing the operating mechanism (96) to move the operator handle (91) to its tripped position. A micro-switch (92) includes an actuator lever (97) movable between an actuated position and a non-actuated position and adapted to engage a surface (95) of the operator handle (91). The micro-switch (92) also includes a normally open contact (98) having a closed state corresponding to the actuated position and an open state corresponding to the non-actuated position. The operator handle surface (95) engages and moves the actuator lever (97) to the actuated position in only the ON position of the operator handle (91). The actuator lever (97) is in the non-actuated position in the OFF position and the tripped position of the operator handle (91).
