Issues when using a thermostat in a DC voltage circuit.
When using in a DC voltage circuit, care must be taken regarding contact wear.
When using a thermostat in a DC voltage circuit, it is important to pay attention to contact wear. Essentially, you should check the contact capacity according to the voltage/DIF. rank. In other words, for example, AC125V and DC12V can both handle up to 5A, while AC250V and DC24V can handle up to 3A at the same current. The mechanism by which contacts wear due to arcing consists of four elements: (a) the magnitude of the voltage, (b) the magnitude of the current, (c) the rate of contact separation and engagement, and (d) the material of the contacts and the condition of the contact surface.
