What Is A Thermal Protector And Why Do Electrical Equipment Need Them?

Thermal protectors are used in electrical equipment to keep them from overheating. These protectors can save lives and money by preventing fires, property damage, and other risks that may arise.

What Is A Thermal Protector

The thermal protector belongs to a kind of thermostat. When the temperature around the electrical appliance rises and cannot work normally and exceeds the temperature setting value of the thermal protector, it will automatically disconnect the circuit to protect the electrical appliance. When the electrical equipment cools down to a safe temperature, the contacts can be automatically closed again, so that the electrical equipment can work normally again.

When Should People Use A Thermal Protector?

A thermal protector is a device that is installed on electrical equipment to maintain the equipment’s temperature while it is in use. Electrical equipment, such as computers, printers, and peripherals, can become extremely hot when they are working, and a thermal protector can help to keep the equipment from overheating and causing damage. In most cases, electrical equipment will need a thermal protector if it is being used in an environment that has a temperature above 65°F (18°C).

Characteristics of A Thermal Protector From Saftty

There are a few different characteristics that should be considered when selecting a thermal protector for electrical equipment.

  1. Effective sealing: These units may avoid product failure brought on by the vacuum impregnation process because they feature effective sealing.
  2. Compact design: The metal casing of Safety’s thermal protection switch is rounded. Because of its tiny size, the motor’s thermal protection switch is simple to embed in the motor’s coil, and temperature detection is more precise.
  3. High-temperature sensitivity and thermal conductivity: Saftty’s thermal protection switch’s metal housing can endure up to 50 kg of coil-shaping pressure. Saftty’s electronic thermal protection switch has a great competitive edge in the market since its rated working temperature may reach up to 250 degrees, making it suitable for application in certain sectors.


Saftty thermal protectors can be used in electrical equipment to prevent overheating and provide overheating protection services for electrical equipment in many fields.
