Actuator lever - used to manually trip and reset the circuit breaker. Also indicates the status of the circuit breaker (On or Off/tripped).
Actuator mechanism - forces the contacts together or apart.
Contacts - Allow current when touching and break the current when moved apart.
Lower and Upper Terminals.
Bimetallic strip - separates contacts in response to smaller, longer-term overcurrent.
Solenoid - separates contacts rapidly in response to high overcurrent
Calibration Screw – adjust thermal tripping rating after assembly
Arc divider/extinguisher – Interrupting the arc to avoid contacts damage
