125 Amp MCB Mini Circuit Breaker / Small Magnetic Trip Circuit Breaker
Desctription:
The DIN rail-mounted thermal-magnetic mini circuit breaker is the most common style in modern domestic consumer unitsand commercial electrical distribution boards throughout Europe. The design includes the following components:
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 - separates contacts in response to smaller, longer-term overcurrents
6. Calibration screw - allows the manufacturer to precisely adjust the trip current of the device after assembly.
7. Solenoid - separates contacts rapidly in response to high overcurrents
8. Arc divider/extinguisher
