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.

basic information
【Features】 ○ The contact gap is primarily an element that counters the magnitude of the voltage, and we guarantee AC250V or DC48V. ○ If a guarantee up to DC75V is requested, only the M2 and M3 Diff. C and D ranks with a larger contact gap will be supported (up to 200mA). ○ The magnitude of the current is primarily related to whether the arc extinguishes or not. ○ It relates to how much damage the contacts receive from the arc. ○ In high current arcs, the thermal rise of the contacts occurs quickly, causing them to melt faster and leading to adverse phenomena such as quicker surface oxidation of the contacts. ● For more details, please contact us or download the catalog.

Company information
I want to be a company that continues to burn brightly. A company can keep burning with energy by having its own unique image. Without it, the company will stagnate and lose its growth potential. Some say that a company's lifespan is 20 years. This may be a lesson suggesting that the length of time one can maintain passion for a single item is limited to 20 years. However, it is also a truth based on past history that a company that can continuously raise new flames can have an infinite lifespan. Of course, it is necessary to continue supplying products that the market demands. However, I believe that is not enough. "Our basic philosophy is to lead the market by understanding market needs and embodying them in our products, while contributing to significant cost savings through continuous technological improvement." While small cost reductions in front of us are certainly necessary, they may be trivial when viewed from a broader perspective. Fundamental reforms that reorganize the system are the root solution. Our goal is to achieve significant cost savings through the rationalization of the overall system.
