mcb outdoor circuit breaker Protect the safety of family members and ensure the safety of staff during use and maintenance.Protect the safety of household appliances to ensure that even in the case of overpressure, still effectively improve the service life of equipment.Protect electricity safety. Ensure electricity safety under harsh environment.
mcb outdoor circuit breaker Space · More flexible:Halved product width saves distribution box space and reduces overall cost,The integrated structure integrates into one body without the need for subsequent splicing.
The miniature Mcb Outdoor Circuit Breaker is composed of the following main components:
1. Separable contact connection. It consists of fixed contacts and movable contacts.
2. A device composed of a metal cylinder or an insulating cylinder, which is equipped with a detachable contact connection, arc extinguishing device and driving device.
When using a miniature circuit breaker to break the circuit, the moving and fixed contacts of the miniature circuit breaker are mechanically separated. When closed, the moving contact and the fixed contact are closed with opposite mechanical movements. When the load circuit is turned on and off, an arc will be generated between the fixed contact and the moving contact. The arc generated during the switching process is much more serious than the arc generated during the switching process. When the breaking current is large, especially when the breaking short-circuit occurs, the arc is large, so it is very difficult to break the circuit.
