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
