Importance of Thermal Protection: Electric motors are crucial in daily life and industrial applications. However, issues like coil blockages or overload can lead to motor burnouts. Thermal protectors, also known as temperature switches, play a critical role by interrupting the circuit when temperatures exceed safe limits.

Choosing the Right Protector:

• Voltage & Current Considerations: Select a protector rated for the motor's voltage (e.g., 380V, 230V) and ensure its current rating exceeds the maximum starting, operating, and blocked currents to avoid premature tripping.
• Temperature Protection: Choose a protector with a set temperature below the motor's maximum allowed temperature (e.g., based on insulation class and installation position inside or outside the coil).
• Protector Types: Decide between pure temperature types (no current thermal effect) and temperature-current double protection types (considering current thermal effects), adjusting the set temperature accordingly.
• Protector Lifespan: Consider the motor's lock-in test duration and choose a protector with a suitable lifespan, ensuring reliability under operational conditions.
• Sealing Performance: Opt for protectors with high sealing capabilities to prevent insulation paint from affecting internal components, particularly crucial for motors undergoing rigorous dipping processes.

Ensure the longevity and efficiency of your electric motors with precise thermal protection solutions tailored to your specific application needs.
