Compound tripping circuit breaker

The present disclosure relates to a compound trip circuit breaker, comprising: a contact system for connecting or disconnecting an external circuit; the tripping structure is connected with the contact system and moves the contact system so as to have a buckling position for enabling the contact system to conduct an external circuit and a tripping position for enabling the contact system to disconnect the external circuit; the first magnetic control loop is used for being electrically connected with an external circuit and is provided with an electromagnetic coil used for actuating the tripping structure to move from the buckling position to the tripping position; the thermal control loop is used for being electrically connected with an external circuit and is provided with a thermal element, the thermal element is used for actuating the tripping structure to move from the buckling position to the tripping position through the thermal inductance deformation piece, and the compound tripping circuit breaker fur
