  • Current measurement device, manufacturing method, protection module and differential circuit breaker including such a device
    Patent number: 10712372
    Abstract: A current measurement device including current sensors positioned around current conductors in order to form a passage for the current conductors along an axis oriented in a first direction and a differential current sensor positioned around the set of current conductors in order to form a common passage for the current conductors along an axis oriented in a second direction. The current sensors and the differential current sensor are located in spaces that are separated by an interface plane. A method for manufacturing such a current measurement device, to a protection module and a differential circuit breaker including such a device.
    Type: Grant
