IEC standards related to panel structural forms

By Shakeer Meeran, 5 Jan 2025 IEC Standards for Panel Structural Forms The IEC defines various standards related to panel structural forms. Below is a summary of key IEC standards along with their descriptions. IEC Standard Number Title Description IEC 60529 Degrees of protection provided by enclosures (IP code) This standard specifies the degree of protection provided by enclosures against the ingress of solid objects and liquids, as denoted by the IP code. The IP code is often used in conjunction with the panel structural forms to define the level of protection provided by the enclosure. IEC 61439-1 Low-voltage switchgear and controlgear assemblies – Part 1: General rules This standard defines the general requirements for low-voltage switchgear and controlgear assemblies, including requirements for the design and construction of enclosures. It references the panel structural forms defined in IEC 60529 to specify the degree of protection required for different types of enclosures. IEC 62208 Empty enclosures for low-voltage switchgear and controlgear assemblies – General requirements This standard specifies the general requirements for empty enclosures used in low-voltage switchgear and controlgear assemblies, including requirements for the design and construction of enclosures. It references the panel structural forms defined in IEC 60529 to specify the degree of protection required for different types of enclosures. IEC 61439-2 Low-voltage switchgear and controlgear assemblies – Part 2: Power switchgear and controlgear assemblies This standard specifies the requirements for power switchgear and controlgear assemblies, including requirements for the design and construction of enclosures. It references the panel structural forms defined in IEC 60529 to specify the degree of protection required for different types of enclosures. IEC 61439-3 Low-voltage switchgear and controlgear assemblies – Part 3: Distribution boards intended to be operated by ordinary persons (DBO) This standard specifies the requirements for distribution boards intended to be operated by ordinary persons, including requirements for the design and construction of enclosures. It references the panel structural forms defined in IEC 60529 to specify the degree of protection required for different types of enclosures. IEC 62271-200 High-voltage switchgear and controlgear – Part 200: AC metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV This standard specifies the requirements for AC metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV, including requirements for the design and construction of enclosures. It references the panel structural forms defined in IEC 60529 to specify the degree of protection required for different types of enclosures.
