Circuit breaker

A circuit breaker comprising:

• a pivotable switching member including a pivoting end and a free end;
• a switch for controlling the connection of a load to a power source, the switch having:
• a fixed contacts, and
• a movable switch contact coupled to the free end of the pivotable switching member and resiliently biased away from the fixed contact, wherein the free end of the pivotable switching member pivots to open and close the main switch;
• a solenoid having a first winding for initially moving the movable contact towards the fixed contact and a second winding for holding the movable contact against the fixed contact;
• a fault detection circuit for detecting a fault at the load and, in response, disabling the solenoid;
• and
• reset means comprising a reset switch for initially energizing the first winding and, when the movable contact is sufficiently close to or reaches the fixed contact, energizing the second winding, the reset switch being mechanically operated by the free end of the pivotable switching member, the pivotable switching member operating the reset switch automatically upon recovery of power supplied by the power source.
