Product functions and applications:

Thermal relays are an important device in the electrical industry. Both used to protect motor overload, circuit and electrical equipment. It also helps to convert circuits of many currents or voltages to different loads because it uses a single control signal extremely efficiently. Besides, it also helps to monitor the entire system of industrial electrical equipment and it will automatically cut off power when suddenly there is a problem. It has a mode to automatically switch off the contacts thanks to the expansion of the metal bars when the temperature rises or falls suddenly.

Today, people still apply the properties of thermal relays to manufacture and to make devices with automatic shutdown when the temperature is exceeded such as: refrigerators, water pumps, water heaters, rice cooker or iron….

Classify:

 Currently, there are many different types of thermal relays on the market. To classify thermal relays, we have to rely on each different criteria to be able to choose the type of relay that is really suitable for the purpose of use:

  • Based on structural criteria: Open relay and closed relay.
  • Based on usage requirements: One-pole thermal relay and two-pole thermal relay.
  • Based on heating method:

          • Direct heating relay

          • Indirect heating relay

          • Mixed heating relay

According to this criterion, the type of mixture relay is most commonly used because it has relatively good thermal stability and is suitable for overloading to help ensure safety for equipment and users.

  • Besides, thermal relays also have other types such as: 3-phase thermal relay, 1-phase thermal relay,....
