Some motors have dual voltage ratings because it is typically better to use the higher voltage if available because the current will be lower. However, the higher voltage may not be available everywhere so the unit is designed to work on the most available voltages if the higher voltage is not available. Since the motor in your question is more for a commercial use than at home, the range of available voltages may be limited at certain sites.

How much voltage in three phase line in electric in India. each phase rating 230V?
If the phase voltage is 230 V, then (providing you are describing a three-phase, four-wire, system), then the line voltage will be 1.732 larger -i.e. 400 V.
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 is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
Can you run a three phase appliance on 240 volt power supply?
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
Vlotage on motor name plate is line or phase voltage?
The voltage tag on a motor says 120 or 220 volt and some motors have jumpers to wire it for either one. That is the supply line voltage. The motor knows how to use that. If the plate says three phase is required then consult your electic supply Company for a three phase supply line.
In a three phase four wire wye system having 277V for lighting the three phase motors operate on what voltage?
480 Volt
What is the different between using the low or high voltage in big three phase motors?
These types of motors are classified as dual voltage motors. The highest motor voltage rating is always double the lowest voltage rating. Dual voltage motors are more versatile in matching the system voltage supply that they are connected to. When the motor uses the highest voltage rating the coil legs are in series, dropping the high voltage across two coils. When the motor is connected to the low voltage rating the coils are connected in parallel dropping the low voltage rating across the two coils in parallel. As you can see no matter which configuration that you use the individual coils can never get a voltage across them greater than the lowest of the two voltages available. The connection diagram is usually on the underside of the motor's junction box lid.

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.
What is full load current rating for 1000kva xmer?
It depends on (1) its voltage rating, and (2) whether it is single phase or three phase. And the symbol for kilovolt ampere is kV.A -not 'kva'.
Can you run a three phase appliance on 240 volt power supply?
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
What is the purpose of dol starter in three phase motor?
Three phase motors are controlled by a device called a starter. The starter allows the motor's supply voltage to be applied to and removed from the motor. These types of starters coil's can be controlled with usually a lower voltage that can be remotely controlled.
What is 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.

What is the US 3 phase voltage?
A balanced three phase system is composed of three single phase voltages having the same amplitude and frequency but displaced from one another by 120 degrees (1/3 cycle).We know that a single coil (winding) rotating in a magnetic field produces a single phase alternating voltage. Similarly, three phase voltage can be produced by a set of three coils separated from each other by 120 electrical degree. Three phase power is so popular because of following advantages.For a given size of frame, a three phase generator or motor has a bigger output than a single- phase machine.To transmit a given amount of power at a given voltage over a given distance, a three phase transmission line requires less copper than a single phase line.Three phase motors are self starting; single phase motors are not self startingParallel operation of three phase alternators is simpler than that of a single phase alternators.
