It is crucial to distinguish between IEC 60947-2 and IEC 60898-1. The fault current the breaker can interrupt and

IEC 60947-2 is an international standard that applies specifically to used in low-voltage electrical installations. It is a core component of the broader IEC 60947 series on low-voltage switchgear and controlgear. IEC 60947-2 is an international standard that applies

| Feature | IEC 60947-2 | IEC 60898-1 | |---------|-------------|-------------| | Primary Application | Industrial | Residential / Commercial | | Maximum Current | 6,300 A and higher | 125 A maximum | | Short-circuit Capacity | Up to 200 kA | 25 kA maximum | | Intended User | Skilled persons only | Ordinary persons | | Trip Characteristics | Broad range (K, Z, MA, etc.) ±20% tolerance | Limited (B, C, D curves) | | Adjustability | Often adjustable | Fixed | | Pollution Degree | Typically higher (e.g., PD3 for severe conditions) | Typically lower (e.g., PD2) |

These definitions are the foundation upon which manufacturers build their products and engineers select them for their systems.

The standard is periodically updated (e.g., the IEC 60947-2:2024 edition) to incorporate new technology and safety practices. Where to Find the Standard You can purchase the official document from: IEC Webstore VDE Verlag Conclusion
