Can i use a circuit breaker with 420V nominal voltage in 520V line voltage nominal current of circuit breaker is 1600A if I can how much current can pass from this circuit breaker?

NO! NO! NO! The circuit breaker must be rated for the line voltage used. Exceeding this limit can cause catastrophic failure! If you are really working on a 1600A bus, stop right now, ang go hire a professional! Your question indicates you are not qualified to work on this gear. YOU ARE GOING TO KILL SOMEBODY. I'm not kidding about this. A breaker that is applied beyond its rating can arc over, and the resulting arc-flash can punch right through the panel cover, spraying vaporized metal on anyone unfortunate enough to be standing there. A 1600A bus can have a fault current of 20,000A OR MORE. This is not something to even think about working on unless you are trained and absolutely know what you are doing!

What is an arc voltage in a circuit breaker?
ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.
Draw and explain the operation of fault voltage ELCB and residual current device?
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means
What is meant by a nominal current?
The word nominal means the lowest possible safe amount. So, nominal current or nominal voltage is the lowest amount necessary to perform an electrical function like keeping a light turned on.AnswerThe original answer is incorrect. 'Nominal' simply means 'named'. So a 'nominal voltage' is the 'named voltage', as opposed to an 'actual voltage'. For example, the nominal voltage of residential supplies in the UK is 230 V; however, this value is allowed to vary between +10/-6% of the nominal voltage. In other words, a nominal voltage of 230 V may vary between 216 V and 253 V.
What is a mcb and what is it used for?
mcb is master circuit breaker. it is used in the circuit for the protection of equipments from over voltage.
What is RRRV in power plants?
Rate of Rise of Re-striking Voltage is a voltage which is found when fault occurs in a power circuit protected by Circuit Breaker. This voltage may be twice the system voltage.
High voltage will trip a circuit breaker?
A higher voltage means that a higher current will flow in the same load. It is the current that causes the breaker to trip.
Do you have a circuit breaker which operates for one millon volts?
Circuit breakers operate on current not voltage.
For voltage drop calculation you must use the current of the circuit breaker or the normal currents?
For voltage drop calculation you must use the current of the load and the distance of the load from the supply source. The circuit breaker is then used to limit the current to the rating of the wire that feeds the load.
Can 11kv breaker be installed on 6.6kv line?
Yes. But,circuit breaker are usually rated in terms of current they can interrupt,not the voltage.
What is an arc voltage in a circuit breaker?
ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.
What happens if a circuit has no resistance?
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
What are the differences between a Miniature Circuit Breaker and normal Circuit Breaker?
An air circuit breaker, or air-blast circuit breaker, is a type of circuit breaker used in high-voltage transmission/distribution systems. It uses compressed air to (a) operate its tripping mechanism, and (b) to extinguish the arc created by a fault current. A miniature circuit breaker is a type of circuit breaker used in low-voltage applications, such as the protection of lighting and power circuits in a domestic residence. It uses a spring to operate its tripping mechanism, and relies on the speed of operation to extinguish the arc created by a fault current. Apart from the fact they are both designed to interrupt a fault current, there is really no other similarity.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
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 size circuit breaker to use on well pump?
Depends entirely on the voltage and current rating of your pump.
Will circuit breaker cause voltage drop in outlet?
A breaker is a current activated device. New to these forums so, not sure on the etiquette of improving the answer above. I didn't see a button to provide a second answer. That being said; While the breaker reacts to current and not Voltage, Voltage drop to a motor load will cause that motor to draw more current, which can trip the breaker. The higher current draw will also create more Voltage drop, etc. Your best bet is just to stay within the industry standard of 3% drop for feeders, 5% for branch circuits. If this question doesn't involve motors, then Voltage drop outside tolerance will eventually cause the device to malfunction, depending on the severity of the drop, but won't effect the circuit breaker.
An example series circuit might be what?
A voltage or current source in series with a circuit breaker or fuse in series with a switch in series with a light bulb.
