IEC 949 is a safety standard that outlines the requirements for electric and electronic equipment used in various applications. The standard covers a broad range of products, including household appliances, industrial machinery, and medical devices. IEC 949 focuses on ensuring that these products are designed and manufactured to minimize risks to users, operators, and the environment.
Result: Using IEC 60949 allows you to safely utilize the cable's capacity more accurately, gaining nearly 5kA of fault capability.
It includes tables for thermal constants (K values) for common conductor materials like Copper and Aluminum , as well as various sheath and armor materials. Typical Calculation Method
: Provides regional access to the standard for various markets. sample calculation
Traditionally, short-circuit ratings were calculated using the , which assumes that all heat generated by a fault remains within the conductor for the duration of the short-circuit. However, in reality, some heat is transferred to the surrounding materials (insulation, screens, and sheaths). IEC 60949 provides a simple method to incorporate these non-adiabatic heating effects , allowing designers to calculate more accurate and often higher permissible short-circuit ratings. Key Calculation Methodology
