Q:Where will the circuit breaker auxiliary contacts be used? ,

generally do not consider maintenance, suitable for branch protection switch, over current release There are two kinds of electromagnetic and electronic

Q:What is the difference between the leakage switch and the general switch?

Molded case circuit breaker product variety, which is characterized by compact structure, easy operation, the function is relatively simple,

Q:Is the zero line going through the circuit breaker?

if there is a device leakage or short shell, circuit breaker (fuse) can not be broken, So that all the lines on the line of the device shell to bring the leakage voltage.

Q:Is the isolator switchable with a circuit breaker?

Circuit breaker: with overcurrent, short circuit automatic trip function, with degaussing arc extinguishing device, can be used to connect, cut off the high current;

Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?

in the maintenance as a clear point, and can not carry sub-gate, or will pull the arc ACCIDENT.

Q:Is the circuit breaker in the circuit necessary?

When the air is open, it is not recommended to use the fuse, need to protect, open the three-phase at the same time off, such as with the fuse

Q:Is the isolator and circuit breaker able to switch to each other?

when the equipment or line is overhauled to ensure safety. In addition, you can also use the disconnector to change the running wiring.

Q:How to distinguish between disconnectors, circuit breakers?

In the closed state can be reliably through the normal load current and short circuit fault curren

Q:Circuit system diagram how the circuit breaker said

Therefore, the disconnector can only be in the circuit has been broken when the circuit breaker to operate, is strictly prohibited with the load operation

Q:Circuit breaker generally choose what ah?

To this end, set the value of RCD, that is, its current I △ n movement, just to escape the normal amount of leakage current value, the value of milliamperes,
