<p>The present invention relates to a circuit breaker (1) comprising an input electrical terminal (100), which is intended to be connected to a storage battery and comprises a body connected at one of its ends to a fixed contact element, an output electrical terminal (200), contact means (3) designed to open or close the electrical contact between the input and output electrical terminals, and means for measuring the current passing through the input electrical terminal. According to the invention, the current measuring means comprise, on the one hand, means for measuring the voltage between two measurement points on the input electrical terminal and means for calculating the intensity of the current from said voltage and, on the other hand, an electrical circuit comprising, in series, a switch and a resistor of known value, said electrical circuit being connected on one side to a point of known potential and on the other side to one of said measurement points, which is placed near the contactor element and the potential of which is measured by the voltage measurement means.</p> |
