NFB: No Fuse Breaker (日系) MCCB : Moulded Case Circuit Breaker (美系) 1. Actuator lever - used to manually trip and reset the circuit breaker. Also indicates the status of the circuit breaker (On or Off/tripped). Most breakers are designed so they can still trip even if the lever is held or locked in the "on" position. This is sometimes referred to as "free trip" or "positive trip" operation. 2. Actuator mechanism - forces the contacts together or apart. 3. Contacts - Allow current when touching and break the current when moved apart. 4. Terminals 5. Bimetallic strip. 6. Calibration screw - allows the manufacturer to precisely adjust the trip current of the device after assembly. 7. Solenoid 8.
