The utility model provides an opening energy storage device for a circuit breaker and the circuit breaker. The opening energy storage device for the circuit breaker comprises a movable end spring seat, a spring pull rod and a stop piece, the stop piece is arranged on the spring pull rod and used for being in pushing fit with the movable end spring seat in the axial direction of the spring pull rod during closing, and the stop piece is in pushing fit with the movable end spring seat through a revolution surface. The radial size of a through hole, allowing the spring pull rod to penetrate through, in the movable end spring seat is larger than the radial size of the spring pull rod. The opening energy storage device provided by the utility model can effectively solve the technical problem in the prior art that the local stress of the movable end spring seat is too large because the extrusion force of the anti-drop nut on the movable end spring seat is relatively concentrated. 本实用新型提供一种断路器用分闸储能装置和断路器。该断路器用分闸储能装置包
