What specific motors are suitable for different types of thermal overload protectors?

Different types of thermal overload protectors are suitable for different types of motors, and the specific selection should be determined according to the power, application scenario, and operating characteristics of the motor. The following are several common types of thermal overload protectors and their specific motors:

1. Thermistor overload protector
Applicable motors:
Low-power AC motors, such as household appliances (such as washing machines, air conditioners, refrigerators, etc.).
Small fans and water pumps.
Features: Fast response speed, simple installation, suitable for low-power equipment that does not require complex protection functions.
2. Thermal relay
Applicable motors:
Small and medium-sized motors in industrial applications, such as pumps, fans, compressors, conveyor belts, etc.
Suitable for a variety of load conditions, especially in manufacturing and processing industries.
Features: Adjustable cut-off current and temperature, suitable for a variety of motor types and working conditions.
3. Electronic overload protector
Applicable motors:
High-power motors, such as motors and compressors in large industrial machinery, and HVAC systems.
Applicable to motors with large load changes (such as cranes, and electric forklifts).
Features: With high accuracy and fast response, it can handle complex protection requirements, including overload, short circuit, and phase loss protection.
4. Temperature switch
Applicable motors:
Small AC motors, such as power tools, household appliances, and small machinery.
Features: Simple and reliable, suitable for applications with low-temperature protection requirements.
5. Thermal protector and current protector combination device
Applicable motors:
Modern equipment and systems, such as motors in smart buildings, and electric vehicles.
Features: Provide comprehensive protection, suitable for occasions with large load changes, and can monitor multiple parameters in real-time.
6. Thermistor relay
Applicable motors:
Small motors and equipment, such as household appliances and power tools.
Features: Simple structure, suitable for equipment requiring basic temperature protection.
7. Intelligent thermal protector
Applicable motors:
IoT devices and high-end motor control systems, are suitable for modern industry and smart buildings.
Features: With remote monitoring and management functions, it is suitable for complex environments that require real-time data analysis and fault warning.
Summary
The selection of a suitable thermal overload protector should be comprehensively considered based on the type, power, and application environment of the motor. Different types of thermal overload protectors differ in terms of protection effect, response speed,d and functional complexity. Reasonable selection can effectively improve the safety and reliability of the motor.
