Abstract (en)
[origin: ES8506177A1] This invention relates to a circuit breaker operating mechanism. The base (70) of the handle (52) moves along grooves or edges (78, 80) on the fixed guiding part formed by the mechanism support plates (40, 42). The grooves (78, 80) determine the trajectory and the fictitious pivoting axis of the handle (52) accurately. Rollers (74, 76) are fitted between the base (70) and the grooves (78, 80) to reduce the friction forces. The switch bar (28) comprises a projection located close to each electrical auxiliary so as to give a remote indication of the state of the circuit breaker and to cause automatic resetting of the auxiliary releases following tripping.
