The International Electrotechnical Commission (IEC) is a global organization that develops and publishes standards for electrical and electronic products. One of its most widely adopted standards is IEC 60947-2, which focuses on circuit-breakers and fuses. In this article, we'll explore the key aspects of IEC 60947-2 and its significance in ensuring electrical safety.
: This is the dedicated segment of the International Electrotechnical Commission standards that deals exclusively with low-voltage circuit breakers (up to 1,000 V AC or 1,500 V DC) intended for use by "skilled" persons in commercial and industrial facilities. iec 60947-2 pdf
: These breakers have no intentional time delay and are not specifically designed for selectivity. They are often current-limiting , meaning they interrupt short circuits extremely quickly (within half a cycle) to minimize damage to equipment. : This is the dedicated segment of the
