The utility model relates to a low-voltage general protector tripping test circuit device, which comprises a high-speed AD conversion module, a main control CPU module, a communication module, a memory module, a clock module, a display module and an action execution module, wherein the main control CPU module is respectively coupled with a high-precision sampling module, the communication module, the memory module, the clock module, the display module and the action execution module; and the high-speed AD conversion module is connected to an upper end and a lower end of a low-voltage general protector, and is connected and installed with the low-voltage general protector in parallel. By adopting the low-voltage general protector tripping test circuit device, a bypass is installed on a general protector to be subjected to tripping test, the low-voltage general protector tripping test circuit device can enter an automatic identification operating state, perform high real-time monitoring on the current operating state, can bypass the general protector immediately once detecting that the general protector actually trips, and reminds people of ''successful tripping test'' and ''operable switching-on'', thus, the operator only needs to switch on the general protector or wait for the general protector to be re-switched on automatically, the low-voltage general protector tripping test circuit device is safe and can operate without cutting off power supply of the general protector.
