The latch holder is composed of a latch part matched with the operating mechanism, and an actuating part matched with the tripping mechanism. The tripping mechanism is composed of a crow plate unit and a drive unit used for driving the crow plate unit to rotate. The drive unit is composed of a conductive member electrically connected with the bimetallic strip, and a magnet yoke arranged on the conductive member. The crow plate unit is composed of a pivotally arranged crow plate. One end of the crow plate is provided with an armature matched with the magnet yoke, while the other end of the crow plate is arranged cooperatively with the actuating part of the latch holder. The conductive member is in a linear arrangement and one end of the conductive member is wound onto the magnet yoke. Due to the adoption of the above technical proposal of the utility model, the attraction force of the magnet yoke is improved.
