Load break switch lbs can play a protective role and is an important part of low-voltage circuit.
1. Distribution box entry. This is the most widely used and effective part.
2. The circuit protected by circuit breaker has no isolation function when equipment maintenance needs isolation.
3. The entrance of capacitor cabinet.
4. Bypass isolation.
5. Isolation before ATS.
6. Isolation of photovoltaic systems.
7. When there is no isolator at the entry point of an important electrical device.
8. Other distribution circuits that need to be cut off and isolated.
