IEC 60947-2 is part of the broader IEC 60947 series, which covers low-voltage switchgear and controlgear. Specifically, Part 2 focuses on with main contacts intended to be connected to circuits with rated voltages not exceeding 1,000 V AC or 1,500 V DC. Core Objectives of the Standard iec 60947-2 pdf
"Absolutely not," Elias said. "The PDF confirms it. Industrial breakers must meet stringent temperature-rise tests, dielectric properties, and resistance to mechanical shock. These things are 'shadow goods'—they copy the look, but they don't follow the science."
By following the guidelines and requirements outlined in IEC 60947-2, we can ensure the safe and reliable operation of electrical systems, protecting people and equipment from potential hazards.

This defines the peak value of an impulse voltage that the equipment can withstand without failure. It measures the breaker’s ability to survive transient overvoltages, such as lightning strikes or switching surges. 3.
