Abstract
A device for short-circuiting an electrical installation that includes at least two electrical conductors, the device including at least two connection terminals, each configured to be connected to a respective electrical conductor, an electromechanical unit configured to establish a short-circuit between the connection terminals, and at least one resistive element configured to connect one of the connection terminals to the corresponding electrical conductor. Each resistive element includes a first connection end connected to the corresponding connection terminal and a second connection end configured to be connected to the corresponding electrical conductor. The resistive element has an impedance, and variation in a value of the impedance is less than 1 mΩ for a temperature of the resistive element of 0° C. to 200° C.
