Claims (16)

1. An electronic trip device (10) comprising a first input terminal (12), a second input terminal (14), a first output terminal (16), a second output terminal (18), a controlled switch (22) installed between the first input terminal ( 12) and the first output terminal (16), and a control circuit (20) configured to issue a command signal (S) intended for a controlled switch (22), characterized in that it contains: - a circuit (30) for measuring the electrical quantity consumed through a controlled switch (22), and - a circuit (24) with finite impedance located between the first output terminal (16) and the second output terminal (18), wherein the control circuit (20) is configured to issue a command signal (S) to open the controlled switch (22) and to monitor the measured electrical quantity (M) when this command signal (S) is issued. 2. Electronic tripping device according to claim 1, wherein the control circuit (20) is configured to generate an indication (I; I') of a defect if the measured electrical quantity (M) indicates a non-zero electrical consumption through the controlled switch (22) when the opening command signal (S) is issued. 3. The electronic shutdown device according to claim 2, wherein the defect indication is a command (I) to turn on the indicator light (34). 4. The electronic shutdown device according to claim 2, wherein the defect indication is defect information (I') transmitted to the user terminal. 5. Electronic shutdown device according to one of paragraphs. 1-4 comprising a human-machine interface (26) configured to transmit local control information (C) to the control circuit (20). 6. Electronic shutdown device according to one of paragraphs. 1-5, comprising a communication circuit (28) configured to transmit remote control information (C') to the control circuit (20). 7. Electronic shutdown device according to one of paragraphs. 1-6, in which the measurement circuit (30) is configured to measure the strength of the current passing through the controlled switch (22), and the specified electrical value is this strength of the current. 8. Electronic shutdown device according to one of paragraphs. 1-7, in which the finite impedance circuit is a resistor (24) installed between the first output terminal (16) and the second output terminal (18). 9. A method for detecting a defect in an electronic trip device (10), comprising a first input terminal (12), a second input terminal (14), a first output terminal (16), a second output terminal (18), a controlled switch (22) installed between the first input terminal (12) and the first output terminal (16), and a control circuit (20) configured to issue a command signal (S) intended for a controlled switch (22), characterized in that the electronic trip device (10) comprises a circuit (24) with a finite impedance located between the first output terminal (16) and the second output terminal (18), the method comprising the following steps: - measure the electrical quantity consumed through the controlled switch (22); - issue (E6) by means of the control circuit (20) command signal (S) to open the controlled switch (22); and - monitor (E8) the measured electrical quantity (M) when the opening command signal (S) is issued. 10. The method for detecting a defect according to claim 9, comprising the step (E10) of generating an indication (I; I') of a defect if the measured electrical quantity (M) shows a non-zero electrical consumption through the controlled switch (22) when a command signal ( S) opening.
