Tips: The main components of the miniature circuit breaker
- Breakable contact connection. It consists of fixed contacts and movable contacts.
- A device composed of a metal cylinder or an insulating cylinder, in which a disconnectable contact connection and arc extinguishing equipment and a transmission device are installed.
- The transmission device that drives the contact.
- Arc extinguishing device.
