What is EN 60947-5-2?

EN 60947-5-2 is a technical standard that specifically applies to low-voltage switchgear and control devices. It defines the requirements for industrial control circuit devices such as pushbuttons, pilot lights, selector switches, and emergency stop buttons. These devices are widely used in various industries to control machinery and equipment.

Importance of EN 60947-5-2

The importance of EN 60947-5-2 lies in its ability to ensure the safe operation of industrial control circuit devices. Compliance with this standard guarantees that these devices meet specific technical requirements, including functionality, reliability, and safety. Manufacturers need to adhere to EN 60947-5-2 when designing, producing, and testing their products to provide users with reliable and safe control devices.

Technical Requirements of EN 60947-5-2

EN 60947-5-2 sets out several technical requirements that control circuit devices must meet. These include electrical ratings, performance characteristics, mechanical design, degree of protection, and resistance to environmental factors such as temperature, humidity, and vibrations. The standard also ensures that devices have appropriate markings and labeling for clear identification and proper usage. Compliance with these requirements ensures that control circuit devices can function effectively and safely.

Testing and Certification

Before control circuit devices can be placed on the market, they need to undergo rigorous testing to ensure compliance with EN 60947-5-2. Testing includes assessing mechanical strength, electrical performance, endurance, and resistance to environmental factors. Only after successfully passing these tests can devices receive certification indicating their compliance with EN 60947-5-2. Users can check the certification marks on control circuit devices to ensure their reliability and safety.
