What circuit breaker rating is commonly used for a radial circuit?

In the terms of voltage it should be in kV but when we are using the current term than it should be in kiloamperes or kA because the short circuit current level of the circuit breaker is very high.
AnswerIt depends entirely on the voltage level and load currents you are talking about. It will be completely different for, say, a 132-kV system than for, say, a 230 V system. So, does your question apply to high-voltage systems or low-voltage systems?

Will a circuit breaker give off less amperage?
A circuit breaker does not give off amperage. A circuit breaker allows a flow of current up to the rating of the breaker. Any current higher than that of the breaker's rating will open the breaker's contacts and stop the flow of current.
Can you replace a 2000 A Circuit breaker with 3150 A rating?
No.
How many ampacity rating do a circuit breaker need for the general purpose circuit?
Usually a 15 or 20 amp breaker is sufficient
What is the proper ampere rating of circuit breaker for electric arc welder?
The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.
What are the breaker ampere trip ratings?
The ampere frame rating for a circuit breaker designates how the circuit breaker should be configured. It also states the trip unit of the amp.
What circuit breaker rating do you need for a 3 phase electric motor?
The circuit breaker is sized to the full load amps of the motor times 250%.
What size amp circuit breaker should be used for a pool light?
The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.
Rating of a 3 pole circuit breaker is the same for each conductor?
Yes, the rating of a 3 pole circuit breaker is the same for each conductor that is connected to it. A three pole breaker rated at 30 amps will have 3 #10 wires from it that connect to the load.
What is the rating of the main circuit breaker of the 60kw power distribution panel?
200 amps
What is a difference between 10KA and 22KA circuit breakers?
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."
What is the maximum voltage for vacuum Circuit Breaker?
The maximum rating or a VCB is 32 KV.The maximum curent rating is up to 3000 A.
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
