Title: What is BS EN 60947-8-2003+A2-2012? A Technical Standard for Low-Voltage Switchgear and Controlgear Devices

BS EN 62973-1:2013 is a technical standard that plays a crucial role in ensuring the safety and proper functioning of electrical appliances. This standard is particularly relevant for electronic appliances with a rated voltage not exceeding 250V, used in domestic and similar environments. The purpose of this standard is to ensure the safety and reliability of electrical appliances, minimizing the risk of electric shock, fire hazards, and other potential dangers.

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 International Electrotechnical Commission (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:

The purpose of BS EN 60947-62 is 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.

Key Requirements and Tests:

BS EN 60947-62 provides manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards. The standard outlines essential tests that manufacturers must conduct to verify the safety and performance of their products. These tests include:

Continuous operation test: This test is designed to verify that the circuit-breaker operates continuously without any interruptions or failures.

Breakover test: This test is designed to verify that the circuit-breaker breaks over the maximum load current without any failures or interruptions.

Short-circuit test: This test is designed to verify that the circuit-breaker opens automatically when a short circuit is detected in the circuit.

Overvoltage test: This test is designed to verify that the circuit-breaker remains closed when the voltage on the circuit exceeds the rated voltage.

Heat test: This test is designed to verify that the circuit-breaker can handle the thermal loads that it is designed to handle.

Conclusion:

BS EN 60947-62 is an essential technical standard that ensures the safety and reliability of low-voltage switchgear and controlgear devices. It is crucial for manufacturers, installers, and users to comply with the requirements and tests outlined in this standard to minimize the risk of electric shock, fire hazards, and other potential dangers. By following the guidelines and requirements set out in BS EN 60947-62, manufacturers can create electrical appliances that are safe, reliable, and meet the highest safety standards.
