If you mean "a" circuit breaker for two (2) three-phase motors, then yes. As long as the rating is not exceeded by the current draw of the two motors. This would, of course, require the use of a three phase breaker arrangement, and power from a three phase source. The question is kind of vague.
Now, just saying that it can be done is one thing, but should it be done? That is where you need to refer to your local authority having jurisdiction (AHJ) over electrical matters.
However, in a normal industrial/commercial setting (3-phase power), an MCC would normally be used, with one breaker/circuit per motor.
What else can I help you with?
Is there continuity between a three pole circuit breaker terminals?
No, the three individual poles of a three phase circuit breaker are not electrically connected to each other. If they were, a fault would develop internal to the breaker.
What is TPN MCCB?
A TPN MCCB is a three phase neutral molded case circuit breaker. This type of circuit breaker is commonly used in low voltage power distribution systems.
What are three phase motors?
Three phase motors are motors which operate under three phase supply.Each phase is displaced from one another by 120 degrees.It produces three fluxes which are also 120 degrees displaced.
Can you power a three phase motor and a 208 motor on the same circuit?
Yes, with the proper control equipment ahead of the motors.
What does a 3 pole circuit breaker do?
It provides power to 3 conductors simultaneously, and more importantly, disconnects all three conductors simultaneously in case of a fault. A three pole breaker is used with a three phase power system.
Why neutral is not required for vacuum circuit breaker?
Air-blast circuit breakers are used to disconnect high-voltage transmission or distribution circuits in the event of a fault. One circuit breaker is required for each of the three line conductors; there is not normally a neutral conductor in high-voltage three-phase transmission/distribution lines.
How many wires are used for a 460 volt circuit breaker?
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
What is 4 pole circuit breaker?
I have never seen a four pole circuit breaker. Breakers are single, two and three pole. Single pole for 120 volts, two pole for 240 volts and three pole for three phase loads. In North America all neutrals are SN (solid neutrals) and are not switched. In certain applications using a three phase Y-connected load, where complete isolation of the load from the supply is required, the neutral line connects to one pole of a 4 pole circuit breaker.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
What is the rating of circuit breaker needed for a 500kva load?
To answer this question a voltage needs to be stated and whether the load is three phase or single phase. Without the voltage the amperage can not be calculated. For single phase, Amps = kva x 1000/voltage, for three phase, Amps = kva x 1000/1.73 x voltage.
What circuit you can use to run three phase motor?
It must be a three phase supply service to run a three phase motor.
