How to Wire Reset Thermal Overload Protector?
Nowadays protection is very important in electrical works, and for different Electrical appliances we use different methods and different devices for protection, today I am writing about overload protectors and their wiring. In this post, I am talking about the automatic reset thermal overload protector that we use for single-phase loads. This overload we use to make safe our electrical devices from over current flowing.
Some Thing About Thermal overload protector relay
Today which type of overload I talking, about is a type of overload switch which is cut off the electric supply in case of overcurrent flowing. This device is also called a reset thermal overload switch. Mostly we use this device for single-phase power supply, and I also published a post about refrigerator overload and its working principles this overload also works the same as refrigerator O/L protector.

How to Wire Reset overload Protector Switch
The over-current overload protector wiring is very simple, and in many places, for single-phase / one-phase supply we use it in series connections between the supply and the load. In the below diagram, I have shown an overload thermal protector which I wired in a series connection. I showed the incoming AC supply and output supply. I connect the L (phase) wire to the protector and then I get the supplied form O/L protector to the load as I have shown below.
In the above diagram, I show 20 A (ampere) overload and whenever it trip you can also reset it by pushing the reset switch. Whenever some over-current flow from its range it will cut off the Electric supply and make his contacts open. Note that always use these overloads regarding your load. If your overloading the current 10 A and you use 20 A then it will not trip until it’s reached 20 Ampere.
Hello, thanks for your explanation. How do I stop this from tripping off. It wouldn't stop doing this since about 4 days now, and it's really annoying. I don't have any water to use. It keep tripping off at about 3 seconds after pushing it back in. Please help before I break it.
The monetary perspectives are very much thought of and consequently to recuperate the expense of innovative work, the reproducers are vested with selective showcasing privileges of the new assortment. In this manner the various sorts of protection, EMF Protectors
