What are the differences between circuit breakers and switches?

Here is mainly to isolate the switch as a target, to specifically look at the difference between the circuit breaker and the isolating switch:

1. The circuit breaker is equipped with arc-extinguishing equipment, which can automatically trip, so it can cut off the load and fault current; and the isolating switch has no arc-extinguishing equipment, so it can not be used to cut off the load and fault current.

2. In the operation mode, the circuit breaker can be remotely controlled by electric power; while the isolating switch is mostly operated manually.

3. The insulation level of the circuit breaker is very low, so it is generally used to handle the load and fault current; the overvoltage capability is very weak, and the isolation switch has a high level of port insulation, generally processing voltage, can not be used Handle load and fault current.

4. The circuit breaker can protect the current line and the motor and cut off the fault current; the isolating switch is generally isolated and operates without load.

The above is about the difference between circuit breakers and switches. Are you familiar with some important electrical installations in your home? Although hydropower projects are more specialized and concealed projects, it is good to know some basic knowledge.
