IEC 60947 is an international standard that outlines the requirements for low-voltage switchgear and controlgear. It covers various electrical devices used for controlling and protecting electrical circuits, ensuring safety and reliability in industrial and commercial applications. The standard is essential for manufacturers and users to ensure compliance with safety regulations. The standard is divided into several parts, each addressing specific equipment types, such as circuit breakers, contactors, and relays. By providing guidelines for design, testing, and performance, IEC 60947 helps maintain consistent quality and safety across electrical installations worldwide.
