Title: What is BS EN 61386 21 and BS EN 60947-62?

Electrical equipment is an essential part of our daily lives, and it is crucial to ensure that it is safe and reliable. 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 the British Standard 476 Part 20 (BS476: Part 20). This standard specifies the requirements for determining the fire resistance of various elements found within buildings such as walls, floors, and doors.

What is BS EN 61386 21?

BS EN 61386 21 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 61386 21 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.

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 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
