Patent ID: 8749329

Claim:
A circuit interrupter for interrupting a current said circuit interrupter comprising: a first contact; a second contact movable with respect to said first contact; a trip arm which moves said second contact between a closed position in which said second contact is touching said first contact and the current is allowed to flow through said contacts and an open position in which said second contact is spaced apart from said first contact so and flow of the current is interrupted; a first trip mechanism through which the current flows when said second contact is in said closed position, said first trip mechanism comprising: a first solenoid, a first overcurrent sensor, and a first arm; a second trip mechanism through which the current flows when said second contact is in said closed position, said second trip mechanism comprising: a second solenoid, a second overcurrent sensor, and a second arm; wherein said first trip mechanism activates said first arm after a first threshold amount of time which actuates said trip arm when said first overcurrent sensor detects a first threshold level; and wherein said second trip mechanism activates said second arm after a second threshold amount of time which actuates said trip arm when said second overcurrent sensor detects a second threshold level, said second threshold level being different than said first threshold level; wherein said first threshold amount of time is different from said second threshold amount of time.
