To do this, we connect one end of the dial tone to any output of the heating element, and the second with a metal "sole" or the body of the kettle. If there is no circuit, then everything is in order. This device will show more accurate readings, so to speak - under operating voltage, but if it is not available, it will be enough to make continuations. As can be seen in the photo, in the case of this kettle the heating element is not damaged. overheating protection This protection should turn off the kettle when there is no water in it, or it has boiled away. The principle of this device is quite simple. When overheating, bimetallic plates on the "bottom" of the kettle bend and press down on the ceramic rods. They, in turn, put pressure on the electric moving contacts, which, when pressed, open. After the bimetal cools and returns to its original state, it also occurs with electrical contacts. They close again and pass current to the heater. And this can continue until someone disconnects the device from the network. Of course, this protection is not designed for multiple disconnections.Most likely, after a couple of dozens of such overheating cycles, the heating element itself will burn, but thanks to it, it may not get to the fire.
