In Industries or any electrical commercial place can be use VCB for protection before the installation of equipment because or system of operation should be safe.
Connection Firs Three phase wire will connect in VCB outdoor chamber R,Y,B then outgoing terminal will used in system supply
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
Actually ACB isused for Low Tension side and VCB is used for High Tension Side..Chappa matter
An alternative to using a fuse is to use an electrical circuit breaker.
You need to be more specific. Do you want a contact telling you if a circuit breaker is on? If that is your question, the answer depends on the model of the breaker.

There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.
A vacuum circuit breaker has the circuit interrupting contacts inside a vacuum bottle. Without air the arc created by interrupting the circuit contains only material from the contacts. As a result the arc cannot sustain itself as well as it would if in air and the contacts will be able to handle higher currents. In an SF6 breaker the arc occurs in SF6 gas. SF6 captures free electrons from the arc quickly quenching it. In the process SF6 is broken apart but will recombine back into SF6. Some "SF6" breakers use vacuum bottles. This results in the small size of SF6 Switchgear with the advantages of vacuum breakers.
To test a circuit breaker, you can use a multimeter to check for continuity and proper voltage. First, turn off the power to the circuit breaker. Then, use the multimeter to test for continuity by placing the probes on the terminals of the circuit breaker. If there is continuity, the circuit breaker is functioning properly. Next, test for proper voltage by turning on the power and checking if the voltage is within the specified range. If the circuit breaker passes both tests, it is functioning properly.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
To use a circuit breaker effectively to protect electrical circuits, follow these steps: Install the circuit breaker correctly according to the manufacturer's instructions. Make sure the circuit breaker is the appropriate size and type for the electrical load. Regularly test the circuit breaker to ensure it is functioning properly. If a circuit trips, investigate and address the cause before resetting the breaker. Do not overload the circuit by plugging in too many devices or appliances. Consider hiring a professional electrician for installation and maintenance if needed.
It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.
