Abstract (en)
[origin: EP3531436A1] An anti-jamming device for an energy storage handle of a universal circuit breaker comprises a circuit breaker body, and an operating mechanism mounted on one side of the circuit breaker body. The energy storage handle is mounted on the outside wall of one side of the operating mechanism. The energy storage handle is rotated to manually store energy for the operating mechanism. The operating mechanism comprises a V-shaped rotating shaft, wherein one end of the V-shaped rotating shaft extends out of one sidewall of the operating mechanism, and the other end of the V-shaped rotating shaft is sleeved with a ratchet which is in linkage with the energy storage handle. A latch which is in linkage with the ratchet is arranged on one side, facing the ratchet, of the energy storage handle. The energy storage handle is rotated to drive the ratchet to rotate through the latch. An anti-jamming structure which prevents the latch and the ratchet from being jammed is arranged between the latch and the ratchet. The anti-jamming structure comprises an anti-jamming plate. The anti-jamming plate is configured to separate the latch from the ratchet when the energy storage handle is in an initial state.
