You can always use a higher voltage rated capacitor, it will probably just last a little longer.

Can you change a 440 volt 12.5 uF start capacitor with a 370 volt 12.5uF run capacitor?

There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.


What will happen if you connect 220v bulb in parallel to 100k ohm resistances with supply of 440 v?

This bulb is very likely to be burn out since the 440 supply voltage is very higher than it's rated voltage.


Can a 230 V capacitor be used for a 440 V application?

Not all capacitors can be used for 220V; There are capacitors that are specially designed to withstand such high voltages.AnswerThe voltage rating of a capacitor is normally expressed as a d.c. value. If you want to use it on a 220-V a.c. system, then you must take into account that 220 V is an rms value, so you must determine its peak value. The peak value of 220 V (rms) is 311 V. So your capacitor must have a rated value in excess of 311 V d.c., or its insulation will fail.


How do you get single phase 440 from three phase 440?

You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.


What size wire do you need for 440 three phase welder on an eight foot run?

The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?

Will a 370 VAC motor run using a 440 VAC capacitor?

If the motor is rated at 370 v and the supply is 370 v, the capacitor needs to be rated at 370 or more volts, so a 440 v capacitor will be OK.


What is the difference between 370 vac and 440 vac capacitors?

The difference is that the 440 vac capacitor has a 70 volt-amp-current higher output than the 370. Capacitors must always be replaced with the same size micro-farads or you'll damage the device, such as a motor. The vac rating can be changed with a capacitor with a higher rating but not lower. Example: 15mfd at 370vac can be replaced by a 15mfd at 440vac, but not the opposite.


Why 440 volts running capacitor if my ac is 230 volts?

The 440 volts listed on the cap is the maximum allowable voltage the capacitor can handle. You could actually use a 370 volt cap on 230 volts. ANSWER; 230 volts AC can it actually be 644 volts peak to peak . It is 44ov because it must be rectified and sees only 324 volt peak which is withing the 440 volt capacitor handling voltage

Can a 440 volt capacitor be used for a 230 volt application?

No. The capacitor will short out and possibly explode. On the other hand, the 440 Volt Cap can be used in a 220 Volt circuit.


The air conditioning work in 230 volt why the compressor use capacitors of 370 and 440 volts if he only need mfd to start?

An AC capacitor is composed of two DC capacitors with the foil ends (-) connected together and the center ends (+) connected to the outside. There are variations to the connections. Each capacitor has to have the voltage rating required by the application -- and there are two capacitors in series in an AC capacitor. A 230V AC capacitor, depending on manufacturing design standard, may not be suitable for starting a 230V air conditioner.


Blower And Capacitor Parts?

The draft boost blower for the Fasco Motor is available as a furnace repair replacement part. It has single speed at 3000 RPM with sleeve bearing. This blower is for heaters, oil and gas furnaces. It operates on 115 volts with 0.7 amps. There are also different kinds of capacitors that can be replaced. The 10m - 370 volt, oval motor run capacitor or the 440 VAC, dual round capacitor can be used as replacements.
