What is BS EN 60947-5-3:2013

Introduction

The BS EN 60947-5-3:2013 standard is a set of technical specifications and requirements for low-voltage switchgear and controlgear equipment. It was developed by the International Electrotechnical Commission (IEC) to ensure safety, reliability, and compatibility in electrical installations.

Scope and Application

The scope of BS EN 60947-5-3:2013 covers electrical equipment used in conjunction with the generation, distribution, transmission, and utilization of electrical energy. This includes equipment such as motor starters, circuit-breakers, contactors, and push-buttons. The standard specifies the necessary characteristics, performance, and testing requirements for these devices to comply with international safety regulations.

Key Requirements

BS EN 60947-5-3:2013 sets out various requirements that must be met by manufacturers and users of low-voltage switchgear and controlgear equipment. These requirements include:

Clear markings and labels on the equipment to indicate its purpose, ratings, and operating conditions.

Protection against electric shock and other hazardous conditions.

Proper insulation and mechanical strength of the equipment.

Resistance to heat, fire, and other environmental factors.

Reliable operation under normal and abnormal conditions.

An effective means of disconnection from the power supply.

Compliance and Certification

Manufacturers of electrical equipment need to ensure that their products comply with the requirements specified in BS EN 60947-5-3:2013. Compliance can be demonstrated through testing and certification by accredited laboratories. Certification marks, such as the CE mark, indicate that the product meets the necessary standards and can be legally sold within the European Union and other participating countries.

Conclusion

The BS EN 60947-5-3:2013 standard plays a crucial role in ensuring the safety and reliability of low-voltage switchgear and controlgear equipment. By complying with this standard, manufacturers and users can have confidence in the performance and compatibility of their electrical installations. It is important to stay updated with the latest revisions of the standard to keep up with advancements in technology and to prioritize the safety of electrical systems.
