1. A module for interconnection between an electrical circuit breaker and an electrical contactor comprising:a housing;
multiple power electrical conductors housed inside the housing, each of the power electrical conductors being configured to electrically connect an electrical output of a circuit breaker to an electrical input of a contactor, in order to supply electrical current to flow from the circuit breaker to the contactor;
a device configured to measure the electrical current that flows through the power electrical conductors;
an electrical voltage sensor configured to detect a voltage between at least two of the power electrical conductors; and
an electronic processor equipped with an interface configured to connect to a data bus and to transmit values of the electrical current measured by the measurement device to the data bus.
