The invention discloses a diode bridge low-inductance module for a circuit breaker. The diode bridge low-inductance module comprises an IEGT press-fitting structure, a diode press-fitting structure, adamping capacitor, a damping resistor and a connecting busbar set; a C-pole conducting plate is shared by C poles of two IEGTs welded in a pressed mode in the IEGT press-fitting structure, and an E-pole arched connecting bar is shared by E poles; a negative electrode conducting plate is shared by diodes welded in a pressed mode in the diode press-fitting structure share, so that electrical connecting lines in most units are removed, the number of the electrical connecting lines is reduced, the loop area is reduced, the structure of the diode bridge low-inductance module is more compact, the space occupation is small, and the cost is reduced; and the branch inductance and the loop inductance of the diode bridge low-inductance module used for a transfer branch of the circuit breaker are greatly reduced. 本发明公开了种用于断路
