Full title and description

STB BS EN IEC 62271-200:2021 + A1:2024 — 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 record describes the 3rd edition (2021) of the IEC 62271‑200 standard consolidated with Amendment 1 published in 2024; it specifies design, ratings, tests and safety requirements for prefabricated metal‑enclosed AC switchgear assemblies for indoor and outdoor use.

Abstract

IEC 62271‑200 defines requirements for prefabricated metal‑enclosed switchgear and controlgear assemblies intended for alternating current, rated voltages above 1 kV and up to and including 52 kV, service frequencies up to 60 Hz, and both indoor and outdoor installation. The standard covers ratings, design and construction, insulation media, earthing, protection against internal arcs, type and routine tests, marking and documentation. Amendment A1 (2024) introduces editorial and technical clarifications consolidated into the published edition.

Scope

The standard is applicable to prefabricated metal‑enclosed assemblies designed for alternating current with rated voltages >1 kV and ≤52 kV, service frequencies up to and including 60 Hz, for indoor and outdoor installation. It covers assemblies that may contain air‑insulated and/or fluid‑filled compartments and applies to the assembly as a whole, supplementing or replacing component product standards where stated. Key scope elements include ratings, insulation levels, earthing, mechanical and electrical performance, internal arc classification and tests, and requirements for type and routine testing.

Key topics and requirements

• Definitions and clause alignment with IEC 62271‑1:2017 (terms such as “assembly”, “in service”, “normal operating condition” clarified).
• Rated parameters: rated voltage, rated insulation levels, rated continuous current, short‑time and peak withstand currents, and rated short‑circuit durations.
• Design and construction requirements for metal enclosures, partitions, removable parts, ventilation, corrosion resistance, IP/IK protection and EMC considerations.
• Insulation media rules (air, liquids, gases), requirements for liquids used in switchgear and related tests.
• Internal arc (IAC) classification and testing (including clarified provisions, LSC category descriptions and IAC test details; certain pole‑mounted IAC requirements are addressed in related standards).
• Earthing circuit specification, rated values and associated test requirements.
• Mechanical requirements and interlock testing; updated mechanical test reduction and clearer force application descriptions for type tests.
• Temperature rise and continuous current (resistance measurement rules updated — resistance measurement required before continuous current test as reference).
• Type tests, routine tests and factory inspection provisions, plus marking, documentation and information to be supplied with assemblies.
• Amendment A1 (2024) consolidates clarifications and limited technical changes into the published text.

Typical use and users

Engineers and designers of medium‑/high‑voltage switchgear assemblies, utility specification writers, manufacturers of prefabricated metal‑enclosed switchgear, test laboratories, certification bodies, inspection and maintenance teams, and procurement specialists use this standard to ensure safe design, manufacture, testing and operation of assemblies rated up to 52 kV. Regulators and contract authors reference it when specifying compliance for power distribution and industrial installations.
