is this coil a single shot solenoid or is it used as a filter i assume you want to know a good value for a varistor to stop voltage spikes from the reverse EMF which is aprox. 4X the input voltage. so i would say to use 2X-3X the input Voltage so 48 or 72 Volt MOV (Metal oxide varistor) You want the varistor to be several volts greater than the peak voltage of the signal across which it is connected. 24 volts is probably the RMS value of the coils voltage. Your varistor must be selected to be greater than the peak voltage. When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby. It renders the power strip useless. But the connected devices are usually spared.

What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
How do you repair contactors?
If it has the correct voltages on the coil and wont pull in to make contact - you replace it. If it pulls in then c;ean the contacts wit a point file and wd40.
What is function of pressure coil in a watt meter?
A 'pressure coil' is an archaic term for a 'voltage coil' (UK terminology) or 'potential coil' (US terminology), as opposed to the 'current coil' in a wattmeter. This coil is connected in parallel with the supply, while the current coil is connected in series with the load.
What is meant by a primary coil and a secondary coil?
In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.
What is difference between 24vac and 240 v ac coil?
These are two different rating coils. I will not take 24V and 240V ac coils in this explanation, I will take low voltage ac coil and high voltage ac coil in the explanation in general. Low voltage ac coils have low insulation in general compared to the high voltage coils since we need more insulation for the high voltage coils. Low voltage ac coils have less no of turns and less diameter of coil compared to high voltage ac coils. But the thickness of the conductor used for the ac coil depends on the current rating of the coil only it does not depends on the voltage.
What is the use of metal oxide varistor disc in Lightning arrestor?
I think your answer is given in previous question -( correct size of varistor across 24v coil) I am just pasting the same here. . . "When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby. It renders the power strip useless. But the connected devices are usually spared. "
How do you wire a omron LY1-O- 24vac switching relay?
Look on the side of the relay case. Here you will find the pin configurations for the C class contacts and the pins that connect to the relays coil to operate the relay.
What is the correct coil pack order in a 1997 silhouette?
what is the correct coil pack firing order for 2001 olds silhouette 3.4 litre
Is this the correct coil for this car?
Well, it could be, but you need to tell us which car and which coil for a better definitive answer.
What is the correct name for the coil or high tension voltage capacitor that Leads to a Spark Plug?
The correct name for the coil that leads to the spark plug is an ignition coil. If you go to a parts store and ask for anything else they will not know what you are talking about.
What are three factors that determine the strength of an electromagnet?
Three factors that determine the strength of an electromagnet are the number of turns in the coil, the material of the core used inside the coil, and the amount of current passing through the coil. Increasing these factors will generally increase the strength of the electromagnet.
How can one determine the torque on the coil in a given electrical system?
To determine the torque on the coil in an electrical system, you can use the formula: Torque Current x Number of Turns x Magnetic Field Strength x Area of the Coil. This formula takes into account the current flowing through the coil, the number of turns in the coil, the strength of the magnetic field, and the area of the coil. By plugging in the values for these variables, you can calculate the torque on the coil in the given electrical system.
What are the factors that determine the amount of induced current?
The factors that determine the amount of induced current in a coil include the rate of change of magnetic flux through the coil, the number of turns in the coil, and the resistance of the coil. Faraday's law states that the induced electromotive force (emf) is directly proportional to the rate of change of magnetic flux.
How do you determine if the motor starters are properly earthed?
by magnetisation of no voltage coil
How do you check an ignition coil on a 02 ford escape have changed the plugs but engine is still missing?
Have vehicle scanned to determine which coil is bad
Have replaced the coil twice on 1999 Dodge stratus to correct code P0352 ignition coil primarysecondary circuit B malfunction. What else can it be?
Test the wiring between the computer and the coil.
Why central ac air handler freeze up?
If you are experiencing freezing on your air handler coil, you may want to check the freon charge to determine if it is correct. Assuming that your thermostat is operating properly, reduced air flow can also cause freezing. Check your filters and other possible blockages such as dirt on the interior coil.
