Surge protection device integrating a current measurement sensor

Surge protection device intended to be installed on an electrical installation, in parallel with one or more items of equipment to be protected, said electrical installation comprising at least one first phase line (L1), a neutral line (N) and an earth line (T), the protection device comprising:

• a casing;
• at least one first and one second busbar, which are housed in the casing;
• at least one first and one second connection terminal, which are housed in the casing and are respectively connected to the first and the second busbars and are respectively intended to be connected to the neutral line (N) and the earth line (T) of the electrical installation;
• at least one first protection module connecting the first busbar and the second busbar, the first protection module being configured to divert a surge current from the neutral line (N) to the earth line (T), or vice versa;
• a current measurement toroid, which is housed in the casing and which comprises a central opening, through which a detection portion passes that forms part of one from among the first and the second busbars, said detection portion being disposed in a surge current diversion path running from the first connection terminal to the second connection terminal,
• wherein the coil comprises a first terminal and a second terminal, which are connected to a printed circuit that is housed in a space provided in the annular support.
