What is the cable size for 600V 3 phase ac motor?
you need the current of motor or the KW/HP rating
What is the starting current of 315 kw 380v motor..pf of .80 percent 3 phase..and what is the circuit breaker to use..sub breaker and main breaker?
starting current of 315 kw motor in start delta 2.5 time for single sec. if your cable lingth 130 meter u can use 150mm2 (3 cable per phase) 150mm2 single cable current 292 Amp voltage drop 0.28/meters so u can use breaker 1000 Amp and set Im time (for starting current) setting avalible in breaker.
Can I run a 12 KW motor with a single phase?
To answer these types of questions, a voltage of the single phase motor should be stated. It has to do with the breaker sizing and wire sizing and current load.
What is maximum motor kw that can be started on direct on line starter?
20 kw
What is the cable size of 110 KW motor?
The cable size depends on a few factors, such as the supply voltage, the method of starting the motor, (direct-on-line, or star delta) and the length of cable required to compensate for voltage drop. Also, if the cable is copper or aluminum.110 kW motor has a rated current of 200 amps at 415 volts, so the correct copper cable size would have a cross-sectional area of 75 square mm., if the motor is started direct-on-line.At 660 volts, the rated current would be 118 volts and the cable size would be 35 square mm.
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
Starting current of 160 kw motor with star delta starting?
Assuming the Motor is IE1 Efficiency and 4 Poles, the in rush current will be 1183 A
What is the starting current for 110 kW motor?
If we consider the rpm to be 1450, then the full load current of 3 phase, 415V motor is approx 190 amps. Now, the starting current of a induction motor is 5-7 times the full load current. Hence the starting current will be approx 950 - 1330 amps. Similar calculations can be made for below mentioned ratings also: 110 KW, 220 V ------F.L. current: 350 amps 110KW, 240 V-------F.L. current: 325 amps
How much transient current for 930 kw motor?
The current depends on the supply voltage.
Why a 750 kw motor takes 17 amps starting current?
The starting current is high because the motor's rotor winding has very low resistance. It's similar to a transformer with a shorted secondary windings. As the motor accelerates,the back emf increases which resist the flow of current in the rotor winding. Hence,the current drop to the rated full-load value.
What is the Full load motor current with a 75 KW drive?
3phese 460 volt 75 kw a/c drivi full load current
What is the cable size for 600V 3 phase ac motor?
you need the current of motor or the KW/HP rating
Can 3.7 KWconverter suitable for 4 KW 3 phase motor?
It depends on what you mean by 'converter'; I'm not aware of such a machine. <<>> No, a 4 kW rotophase will not handle the start up current of a 4 kW 3 phase motor.
What is the starting current of 315 kw 380v motor..pf of .80 percent 3 phase..and what is the circuit breaker to use..sub breaker and main breaker?
starting current of 315 kw motor in start delta 2.5 time for single sec. if your cable lingth 130 meter u can use 150mm2 (3 cable per phase) 150mm2 single cable current 292 Amp voltage drop 0.28/meters so u can use breaker 1000 Amp and set Im time (for starting current) setting avalible in breaker.
You have 3.7 kw 5 hp motor is their how much ian amps?
current = power/ voltage current = 3700/ 240 = 15.4 amps
What is the Difference maximum unit current draw and nominal unit current draw?
Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
How many watts in 0.32 kw?
0.32kW is 320 watts.
