HCET-A Series Overcurrent and Overheating Protector

December 06, 2023

As industrial and domestic electricity loads continue to increase, more and more electrical equipment will have problems such as overcurrent and overheating during operation. If measures cannot be taken in time to protect them, it will have serious influence for personal safety and the integrity of the equipment. In order to avoid this situation, people began to widely use overcurrent and overthermal protectors. As one of the representative products, the HCET-A series overcurrent and overthermal protectors have also attracted much attention for their principles, functions and applications.

1. Principle of HCET-A series overcurrent and overheating protector

HCET-A series overcurrent and overheating protector is a protection device with bimetallic sheet as the core. In the circuit, when the current passes through the bimetal, it will bend due to the force of the current, thus closing the protection loop. At the same time, when the bimetal is exposed to heat, it will also bend and open the protection circuit. In this way, when electrical equipment experiences abnormal conditions such as overcurrent and overheating, the low-resistance switch will be triggered, and the protection circuit will immediately cut off the power supply to protect the equipment.

 

In the production of bimetallic sheets, HCET-A series bimetal thermal protectors use high-quality materials and precision processing technology. Through multiple steps such as processing, stamping, and forming, the bimetallic sheet has good mechanical properties and high-precision dimensional requirements, thereby ensuring its reliability and stability in the circuit.

2. Functions of HCET-A series overcurrent and overheating protectors

 

● Overcurrent protection function

Overcurrent protection is one of the main functions of the HCET-A series overcurrent and overheating protectors. It can accurately judge the overcurrent situation of electrical equipment and cut off the power supply in time to avoid equipment damage or safety accidents due to overcurrent.

 

● Overheating protection function

Overheating protection is another important function of HCET-A series overcurrent and overheating protectors. The bimetallic piece used in this device can sensitively sense the temperature changes of the equipment and will automatically cut off the power supply once the temperature is too high. This can effectively protect the equipment and extend its service life.

 

● Temperature control function

In addition to overcurrent and overheating protection functions, HCET-A series overcurrent and overheating protectors can also stably control the temperature of the equipment. In some applications, the operating temperature of the equipment needs to be strictly controlled to ensure the normal operation of the equipment and avoid damage or accidents due to excessive temperature.

 

3. Application of HCET-A series overcurrent and overheating protectors

● Industrial field

In the industrial field, electrical equipment is used frequently, and overcurrent, overheating, etc. often occur. HCET-A series overcurrent and overheating protectors can effectively detect and protect these abnormal conditions. This device is widely used in various types of machine tools, production lines, engineering machinery, heavy equipment and other fields.

● Household appliances field

With the continuous development of smart home appliances, people have put forward higher requirements for the safety and protection of home appliances. HCET-A series overcurrent and overheating protectors are widely used in the field of home appliances. They can protect electrical equipment such as televisions, air conditioners, refrigerators, washing machines, and electric fans to ensure the safety of household electricity.

● Other fields

In addition to the above two fields, HCET-A series overcurrent and overheating protectors can also be used in other industries such as medical equipment and transportation. For example, it can protect electric vehicles and ensure safe operation under high temperature, overload and other conditions.

 

In short, HCET-A series overcurrent and overheating protectors, as an important electrical protection device, have been widely used in various fields. Its characteristics such as high sensitivity, fast response speed and strong reliability make it an indispensable part of modern electrical systems.
