More Information
Summary:The utility model provides an action assembly and a circuit breaker, and relates to the technical field of low-voltage electric appliances, an electromagnet directly drives a button to move, that is, an intermediate transmission part is not additionally arranged between the electromagnet and the button, so that the transmission efficiency and the closing speed can be effectively improved, the electrical wear is reduced, and the electrical life of the circuit breaker is prolonged. In addition, the switch further comprises a permanent magnet, the permanent magnet can be located on the electromagnet, and the magnetic field directions of the permanent magnet and the electromagnet are the same, so that the magnetic fields of the permanent magnet and the electromagnet are superposed, the driving force to the button is further increased, and the switching-on speed can be further increased; and the permanent magnet is added to provide enough acting force for the circuit breaker mechanism during over-travel, so that t
