[0002] An electromagnetic tripping device is a type of tripping device that only provides magnetic protection, that is, short-circuit protection. It is actually a magnetic return force. When the current is large enough, the magnetic force generated overcomes the reaction spring to suck in the armature and strike the traction rod, thereby driving the mechanism to operate and cut off the circuit.

[0003] Chinese Patent No. CN214705841U discloses an electromagnetic tripping device, including a tripping device body. The tripping device body includes a tripping latch and a locking latch that are rotatably installed on the tripping device housing, a tripping spring that provides an elastic acting force for the tripping latch, and a tripping rod that is linked to the tripping latch. After the tripping latch disengages from the locking latch, it rotates under the elastic acting force of the tripping spring and drives the tripping rod to move. The tripping spring is a helical compression spring, and the elastic force direction of the helical compression spring is the same as the movable direction of the tripping rod. The electromagnetic tripping device in the utility model has a reasonable structure, reliable and stable product action characteristics, and is convenient for assembly.

[0004] Although the above-mentioned electromagnetic tripping device has reliable and stable product action characteristics, it requires installation tools during installation, and the installation operation is inconvenient.

A switch component 8 is installed on one side of the release 7, and a buckling part 801 is provided at one end of the switch component 8;

[0026] Specifically, when the current is large, the current passing through the coil 5 will increase, the generated magnetic field will be large, and the generated electromagnetic force causes the armature 2 to rotate towards the coil 5 and push the iron core 6 to move to the right. The iron core 6 presses against the release 7, causing the release 7 to rotate. The clamping part 701 of the release 7 is separated from the buckling part 801 of the switch component 8, causing the switch component 8 to disconnect and complete the release operation;
