Title: What is BS EN 60947-62 and BS EN 60947-5-1:2017?

Introduction:

Electrical equipment is an essential part of our daily lives, and it is crucial to ensure its safety and performance. One of the most critical components of electrical equipment is the circuit-breaker. A circuit-breaker is a crucial device that protects electrical circuits from overload, short-circuit, and other faults that could lead to damage or fire. To ensure the safe operation and performance of circuit-breakers, the International Electrotechnical Commission (IEC) has developed BS EN 60947-62 and BS EN 60947-5-1:2017.

What is BS EN 60947-62?

BS EN 60947-62 is a technical standard that specifies the requirements for low-voltage switchgear and controlgear devices. It is part of a series of standards developed by the IEC to ensure the safety and performance of electrical equipment. This particular standard focuses on the requirements and tests for circuit-breakers.

The Purpose of BS EN 60947-62:

BS EN 60947-62 aims to ensure the safe operation and performance of circuit-breakers. Circuit-breakers are crucial devices that protect electrical circuits from overload, short-circuit, and other faults that could lead to damage or fire. They are designed to interrupt the flow of current when necessary, preventing any potential harm to the electrical system or people around it.

The purpose of this standard is to provide manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards.

Key Requirements and Tests:

BS EN 60947-62 has several key requirements and tests that manufacturers must meet to ensure the safety and performance of their circuit-breakers. These requirements and tests include:

1. Electrical Safety: The device must be designed to ensure electrical safety. This includes ensuring that the device is resistant to electrical currents, and that it does not pose a risk of electrical shock or fire.

2. Electrical Performance: The device must be able to perform as expected under a variety of electrical conditions. This includes ensuring that the device can handle the maximum voltage and current that it is designed to handle, and that it does not experience any significant degradation in performance over time.

3. Safety Performance: The device must be able to perform safely in a variety of environments. This includes ensuring that the device is resistant to overheating, and that it does not pose a risk of fire or other safety hazards.

4. Environmental Stability: The device must be able to withstand the environmental conditions that it will be subjected to. This includes ensuring that the device is resistant to moisture, dust, and other environmental factors that could affect its performance or safety.

BS EN 60947-5-1:2017:

BS EN 60947-5-1:2017 is a technical standard that specifies the requirements for low-voltage switchgear and controlgear devices. This standard is applicable to devices such as circuit-breakers, switches, contactors, and motor-starters, which are used in electrical installations.

Key Features of BS EN 60947-5-1:2017:

1. Electrical Safety: The device must be designed to ensure electrical safety. This includes ensuring that the device is resistant to electrical currents, and that it does not pose a risk of electrical shock or fire.

2. Electrical Performance: The device must be able to perform as expected under a variety of electrical conditions. This includes ensuring that the device can handle the maximum voltage and current that it is designed to handle, and that it does not experience any significant degradation in performance over time.

3. Safety Performance: The device must be able to perform safely in a variety of environments. This includes ensuring that the device is resistant to overheating, and that it does not pose a risk of fire or other safety hazards.
