What is EN 60335-2-103:2020?

EN60335-2-103:2020 is a technical standard that specifies safety requirements for household and similar electrical appliances. It is part of the EN60335 series, which covers various aspects of electrical appliance safety. This particular standard focuses on the safety requirements for thermal-links used in electric motors.

The Importance of Thermal-links

Thermal-links play a crucial role in preventing overheating and potential fire hazards in electric motors. They are small devices that are sensitive to temperature changes. When the temperature exceeds a certain threshold, the thermal-link activates and breaks the electrical circuit, thereby protecting the motor from overheating. This prevents any further damage and reduces the risk of fires caused by electrical appliances.

EN60335-2-103:2020 provides detailed specifications for thermal-links based on their intended use in different types of motors and appliances. These specifications include parameters like operating temperature range, response time, and current carrying capacity. Manufacturers need to ensure that the thermal-links they use in their products meet the requirements outlined in this standard.

Compliance with EN60335-2-103:2020

To ensure compliance with EN60335-2-103:2020, manufacturers of electrical appliances must follow specific procedures and guidelines during the design, production, and testing stages.

Firstly, they need to select thermal-links that meet the standard's specifications and are suitable for the intended application. The thermal-links should be able to handle the anticipated temperatures and respond appropriately within the required time frame.

In addition, manufacturers must conduct thorough testing on their appliances to verify compliance with the standard. This includes evaluating the performance of the thermal-link under normal operating conditions and in worst-case scenarios. The appliances should also undergo safety tests to ensure that they meet other relevant requirements specified in the EN60335 series.

Conclusion

EN60335-2-103:2020 is an essential standard that promotes the safe use of household and similar electrical appliances. By setting out specific safety requirements for thermal-links used in electric motors, the standard helps prevent overheating-related accidents and potential fires.

Manufacturers play a crucial role in ensuring compliance with this standard by carefully selecting appropriate thermal-links and conducting thorough testing on their appliances. Compliance with EN60335-2-103:2020 ultimately contributes to the overall safety and reliability of electrical appliances in our homes.
