What is the difference between 60947-2 and 60947-3 ?

Title: What is the Difference between 60947-2 and 60947-3? A Comprehensive Comparison

Electrical engineering is a critical sector where safety, compatibility, and reliable operation are of paramount importance. Standards play a crucial role in ensuring that electrical equipment operates correctly and efficiently. Two widely referenced standards in this field are IEC 60898 and IEC 60947- While both standards focus on low-voltage circuit breakers, there are significant differences between them. This article will explore these dissimilarities, shedding light on their specific applications, performance characteristics, and regulatory frameworks.

IEC 60898: The Standard for Circuit Breakers for Overcurrent Protection

IEC 60898 is an international standard that specifies the tests and measurement methods for circuit breakers used for overcurrent protection. This standard is divided into four parts, which cover the different aspects of circuit breakers, including their design, testing, and documentation.

One of the main differences between IEC 60898 and IEC 60947-2 is their scope. IEC 60898 is specifically focused on circuit breakers for overcurrent protection, while IEC 60947-2 is a general-purpose standard that covers low-voltage circuit breakers.

Another significant difference between the two standards is their approach to overcurrent protection. IEC 60898 focuses on the thermal aspects of circuit breakers, ensuring that they can handle high currents without overheating and causing damage to the device. On the other hand, IEC 60947-2 has a more conservative approach, focusing on the mechanical aspects of circuit breakers, ensuring that they can handle high currents without causing damage to the device or the circuit.

IEC 609472: The Standard for Low-Voltage Circuit Breakers

IEC 609472 is an international standard that specifies the tests and measurement methods for low-voltage circuit breakers. This standard is divided into four parts, which cover the different aspects of circuit breakers, including their design, testing, and documentation.

The primary goal of IEC 609472 is to ensure the safety and reliability of low-voltage circuit breakers. This standard takes a holistic approach to circuit breakers, considering factors such as the environment in which the circuit breakers will be used, the types of loads they will protect, and the operating conditions.

Difference between 609472 and 609473:

While both IEC 609472 and IEC 609473 are standards for low-voltage circuit breakers, there are significant differences between them. The primary difference between the two standards is their scope.

IEC 609472 is a general-purpose standard that covers a wide range of low-voltage circuit breakers, including high-temperature and thermal-based breakers. On the other hand, IEC 609473 is a specific standard that focuses on thermal-based breakers, designed to handle high currents without overheating.

Another significant difference between the two standards is their approach to thermal protection. IEC 609472 has a more aggressive approach, focusing on the thermal aspects of circuit breakers, while IEC 609473 has a more conservative approach, focusing on the mechanical aspects of circuit breakers.

Conclusion:

In conclusion, while both IEC 60898 and IEC 609472 are standards for low-voltage circuit breakers, there are significant differences between them. IEC 60898 is focused on the thermal aspects of circuit breakers, while IEC 609472 is a general-purpose standard that covers a wide range of low-voltage circuit breakers. On..
