Claim 2:
3. The contactor of claim 1, wherein the controller is configured for:
a) repeatedly measuring a primary current flowing through the electrical conductor portion using the magnetic sensor;
b) detecting if an overcurrent condition occurred based on the measured primary current, and if it is detected that an overcurrent occurred, continuing with step c);
c) determining an available time period (Δtav) to open the primary switch;
d) comparing the available time period (Δtav) and a required time period (Δtreq) to open the primary switch, and if the available time period is smaller than the required time period, continuing with step f); otherwise continuing with step e);
e) operating the actuator to open the primary switch;
f) detecting whether the primary switch is effectively open, and in case the primary switch is still closed after the available time period (Δtav), blowing the fuse.
