A miniature circuit breaker with quick current breaking capability which includes a miniature circuit breaker body, a current transformer CT1, a zero-sequence current transformer CT2 and a smart controller module. The miniature circuit breaker body is internally provided with a main arc extinguishing chamber, a fixed contact, a movable contact, a tripping mechanism, and a magnetic tripping push rod. The tripping mechanism includes a lock catch, a movable contact rocker arm, a jump pin, a connecting rod, and a tension spring. A rotated-hinge repulsive force structure is applied between the fixed contact and the movable contact. The tripping mechanism is further provided with a torsional spring to press the movable contact close to the fixed contact. A shunt tripping device controlling the miniature circuit breaker switch to be turned off is arranged in the smart controller module.

A moving contact mechanism with a contact support that rotates around a third axis, a moving contact pivotable around a contact axis, and both ends of the contact spring are a third end of the spring and a fourth end of the spring, respectively, which are rotatably connected to the moving contact and the contact support respectively. A geometric axis of the contact spring is a second axis line located on one side of the third axis when the moving contact is normally on or off. The contact spring keeps the moving contact in an on or off state. The moving contact rotates relative to the contact support when repelled, drives the contact spring to rotate around the fourth end of the spring, so that the second axis line swings to the other side of the third axis, and remains in a temporary breaking position.
