The world of electrical engineering does not stand still, and neither does IEC 60947-2. The was published in September 2024, replacing the fifth edition from 2016 and its 2019 amendment. This new edition constitutes a technical revision with several significant changes that professionals must understand.

IEC 60947-2 is a standard published by the International Electrotechnical Commission that specifies requirements for circuit-breakers and fuses. The standard is part of a series of IEC standards for low-voltage switchgear and controlgear, and it provides a framework for the design, testing, and performance of circuit-breakers and fuses.
