These distances are influenced by voltage level, pollution degree, and the system insulation category. The IEC 61439-1 standard is the most commonly used document for defining these values. It applies to low-voltage switchgear and control gear assemblies and provides a table of minimum clearances. Creepage distance is. Clearance (Distancia de Aislamiento en Aire): The shortest physical distance in air between two active conductive parts (or between a conductor and a grounded metal frame). Creepage. Use this advanced clearance and creepage calculator to determine the minimum required distances for electrical insulation in your designs. Ensure compliance with safety standards like IEC 60664-1 by accurately calculating clearance (through air) and creepage (along surface) based on operating. The test shall be carried out according to IEC 60068-2-2 Test Bb, at a temperature of 70 °C, with natural air circulation, for a duration of 168 h (7 days) and with a recovery of 96 h (4 days).
