thermik s01 cut off switch

Product Item: thermik s01 cut off switch
Category: Miniature thermal protector
ST01 series thermal protector
Product advantages:
• Obtained UL and TUV certification, breaking Germany's thirty-year monopoly protector.
• Good airtightness, which can prevent product failure during the vacuum dipping process.
• Small size, suitable for being buried inside the coil.
• Metal shell, can withstand 50KG coil shaping pressure, has good thermal conductivity, and is sensitive to temperature.
• Pure temperature products, the current does not pass through the two chips, there is no current heating effect, and the temperature control is accurate.

Competitive Advantage :
ST01-U4 ultra-temperature protection thermal protection epoxy encapsulation, more suitable for preventing vacuum impregnation areas. Small size, easy installation. Sensitive, reliable performance, the indicators reached the international advanced level.
