[0022] Embodiment 1

[0023] Such as Figures 1-4As shown in the figure, this is the first embodiment of the present utility model. This embodiment provides an electrical fire prevention current limiting protector, which includes a protection component 1. The protection component 1 includes an end cover 101 and a rear cover 102. A monitoring component 2 is installed on the surface of the protection component 1. The monitoring component 2 includes a microcontroller 201, a display 202, a circuit breaker switch 203, a current sensor 204, a voltage sensor 205, a wireless transmission module 206, and a buzzer alarm 209. The microcontroller 201, the current sensor 204, the voltage sensor 205, and the wireless transmission module 206 are all installed in the inner cavity of the rear cover 102. The display 202, the circuit breaker switch 203, and the buzzer alarm 209 are installed on the surface of the end cover 101. The output ends of the current sensor 204 and the voltage sensor 205 are both connected to the input end of the microcontroller 201.

[0025] Embodiment 2

[0026] Referring to Figures 1-4 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0032] As Figures 1-4 shown, through the cooperation of the card slot 103 and the elastic bayonet 104, the current-limiting protector can be installed in the distribution box. The thermistor 210 can monitor the operating temperature of the cable. The model of the thermistor 210 can be selected as S900J.
