ST01 series temperature switch
Product advantages:
• Same thermal protection function, low price
• Obtained UL and TUV certification, breaking Germany's 30-year monopoly on temperature switches.
• 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 flow through the bimetal, no current heating effect, accurate temperature control.
technology:
• Integrate global supply chain resources, and the bimetallic sheet uses materials from the world's largest manufacturer, the United States EMS. The shell adopts the stamping and forming technology of German supplier.
• The reed is made of Japanese NGK material, which is processed and produced by Japanese stamping parts suppliers.
• The shell and reed are silver-plated, which greatly reduces the contact resistance.
• The core components of the two pieces adopt fully automated molding equipment and temperature screening tunnel kiln production testing, with good consistency and stable performance.

Custom Built in Thermal Fuse link and cable
The thermal fuse is a thermal protector. Thermal fuses are mainly composed of melts and tubes, plus external fillers. When using, connect the thermal fuse in series with the protected circuit. When the current of the protected circuit exceeds the specified value, and after a certain period of time, the melt generated by the melt itself fuses the melt, breaking the circuit, thereby protecting the circuit. Electrical appliances that use a metal conductor as a melt to break a circuit are connected in series in the circuit.
thermal fuse and circuit breaker cutoff temperature
They are the same in that they can achieve short circuit protection. The principle of a thermal fuse is to use a current flowing through a conductor to cause the conductor to heat up. When the melting point of the conductor is reached, the conductor is melted so that the circuit-protected electrical appliances and lines are not burned.
Thermal Fuse Function and Application
The Thermal Fuse (Thermal Cutoff, Temperature Fuse) is Axial / Radial / Organic Thermal-Link(OTCO) safety parts that stops the flow of electricity to the motor circuit when a overheats. If the fuse is missing or broken, your motor will not start. The thermal fuse is sensitive to external temperature, and the operating temperature is accurate and stable. Küçük boy, mühürlü yapı. Güvenilir performans. Low resistance value. Tek seferlik eylem akımı keser, and the current interruption capacity reaches 250VAC/25A.
