What are the applicable scenarios of different types of AC thermal protectors?

Different types of AC thermal protectors are suitable for different scenarios and equipment. The following are several common types of AC thermal protectors and their applicable scenarios:

1. Thermistor protector
Applicable scenarios: small power AC motors, such as household appliances (such as washing machines, and refrigerators) and small fans.
Features: simple installation, low cost, suitable for equipment that does not require complex protection functions.
2. Thermal relay
Applicable scenarios: AC motors in industrial equipment, such as pumps, fans, compressors, etc.
Features: adjustable cut-off temperature and overload protection, suitable for a variety of load conditions, widely used in manufacturing and processing industries.
3. Electronic thermal protector
Applicable scenarios: high-power or high-load AC motors, such as motors in large industrial machinery and HVAC systems.
Features: fast response speed, high accuracy, and multiple protection functions (such as overload, and phase loss protection), suitable for complex systems.
4. Temperature switch
Applicable scenarios: simple AC motor protection, such as small motors and equipment (such as motors in household appliances).
Features: simple and reliable, suitable for applications that do not require complex control.
5. Combined device of thermal protector and current protector
Applicable scenarios: modern equipment and systems, such as intelligent building management systems and high-end industrial equipment.
Features: Provides comprehensive protection, is suitable for occasions with large load changes, and can monitor multiple parameters in real-time.
6. Thermal relay
Applicable scenarios: small motors and equipment, such as power tools and small machinery.
Features: Simple and easy to use, suitable for applications requiring basic temperature protection.
7. Intelligent thermal protector
Applicable scenarios: IoT devices and intelligent motor control systems, suitable for modern intelligent buildings and industrial automation.
Features: Remote monitoring and management functions, are suitable for environments requiring real-time data analysis and fault warning.
Summary
The selection of a suitable AC thermal protector should be determined according to the specific application scenario, equipment type, and working environment. Different types of thermal protectors differ in terms of protection effect, response speed, and functional complexity. Reasonable selection can effectively improve the safety and reliability of the equipment.
