Abstract
An overcurrent protection device includes a first input terminal, a second input terminal, a first output terminal, a second output terminal, a breaker, a current sensor, and a comparator. A positive terminal and a negative terminal of a power source are connected to the first input terminal and the second input terminal. The second output terminal is connected to the second input terminal. The breaker includes a switch connected between the first input terminal and the first output terminal and opening upon reception of an interrupt command signal. The current sensor measures a difference between a current flowing between the first input terminal and the first output terminal, and a current flowing between the second input terminal and the second output terminal. The comparator sends the interrupt command signal to the breaker when a measurement value of the current sensor exceeds a first current threshold value.
