Claim 2:
3. A unipolar switching module comprising:
a case made of insulating material;
a contact system associated with electrical connection terminals and an arc extinguishing system; and
a set;
wherein the contact system is selected from the group consisting of a rotary contact system and a double rotary contact system;
wherein the set is selected from the group consisting of a thermomagnetic tripping set associated with one of the electrical connection terminals and a current measurer and power supply set associated with one of the electrical connection terminals;
