CB AND RELAY
RELAY.
1. Actuator mechanism -forces the contacts together or apart
2. Contacts - Allow current when touching and break the current when moved apart
3. Terminals
4. Bimetallic strip.
5. Calibration screw -allows the manufacturer to precisely adjust the trip current of the device after assembly.
6. Solenoid
7. Arc divider/extinguisher
