Mell How do I know how many amps my 3 phase heater is?
Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.
How many amps does a 1kw heater use?
kW To Amps Calculator
| Power (kW) | Voltage (220 V) | Amperage (A) |
|---|---|---|
| 1 kW to Amps: | 220 V | 4.55 Amps |
| 2 kW to Amps: | 220 V | 9.09 Amps |
| 4 kW to Amps: | 220 V | 18.18 Amps |
| 6 kW to Amps: | 220 V | 27.27 Amps |
How to calculate three phase kilowatts to amps?
Calculation of AC three phase Kilowatts to amps. I (A) = 1000 x P (kW) / (√3 x PF x V L-L (V)). It means that the phase current in amps is computed by 1000 multiplied by the power in kilowatts divided by the square root of three multiplied by the power factor times the line to line voltage RMS in volts.
How to calculate the power of a 3 phase heater?
Use the Ohm’s law formula: Power (watts) = Voltage (volts) x I current (amps). Arrange the equation for three-phase power to solve the current (amps): Current (amps) = power (watts) ÷ voltage (volts) ÷ square root of 3 (1.732) ÷ power factor; I = P ÷ (V_1.
How many amps does a 2KW electric heater draw?
What is 2kw in amps? A 2Kw 230 volt rated heater will draw 8.69 amps at 230 volts,at 240 volts the same heater will draw 9.07 amps giving 2177 watts and at 220 volts the same heater will draw 8.31 giving 1820 watts,as you can see the Amps and Watts vary with the voltage.
What is the current per phase of a 5kw heater?
If it is phase to neutral voltage, then each (5kW) heater has across it 360V RMS (208 V × 3) and this means a current of 13.88A per phase. If 208V is your line voltage, then the current per phase will be 24A.
