mcb miniature circuit breaker box advantage
Three-level current limit, fast closing, the green sign on the handle clearly indicates that the contact is in the open position, the front window is red to indicate the circuit breaker tripping, the accessories are complete, powerful, and the over-voltage and under-voltage integrated protection accessories are added.
Commonly used miniature Mcb Miniature Circuit Breaker Box break the circuit by mechanically separating the movable contact and the fixed contact of the miniature circuit breaker. When closing, the moving contact and the fixed contact are closed by the opposite mechanical movement. During the operation of connecting and breaking the load circuit, an arc will be generated between the fixed contact and the moving contact. The arc generated during the breaking process is much more serious than the closing process. When the breaking current is large, especially when the breaking short circuit occurs, the arc is large, and it is often very difficult to break the circuit.
mcb miniature circuit breaker box consists of the following main parts:
1. Breakable contact connection. It consists of fixed contacts and movable contacts.
2. 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.
3. The transmission device that drives the contact.
4. Arc extinguishing equipment.
Short circuit protection, isolation function, use with thermal relay or motor starter to achieve overload protection, suitable for low-voltage terminal power distribution in the fields of medical IT power distribution system, motor protection and building fire protection system.
