The apparatus indicates the maximum threshold value reached by an electric current in a circuit characterised in that it consists of a voltage divider formed by several resistors 41 to 49 connected in series, the end terminals of which divider are connected to the shunt Sh itself connected in the circuit whose current is to be measured. Each resistor 41 to 49 of the voltage divider establishes an excitation voltage for the control electrode of a component with a conduction threshold 19 to 27 connected to a DC voltage source 28, in series with an electroluminescent component 1 to 9. <IMAGE>
