Full title and description

IEC 62271-100:2021+AMD1:2024 (Ed. 3.1) — High-voltage switchgear and controlgear — Part 100: Alternating‑current circuit‑breakers. Consolidated 2024 edition (CSV) incorporating Amendment 1:2024 and applicable corrigenda; provides requirements, ratings and direct testing methods for three‑phase AC circuit‑breakers for systems above 1 000 V.

Abstract

This consolidated 2024 edition (IEC 62271-100:2021+AMD1:2024 CSV, Ed. 3.1) is applicable to three‑phase AC circuit‑breakers designed for indoor or outdoor installation and for operation at 50 Hz and/or 60 Hz on systems having voltages above 1 000 V. It includes direct testing methods for making‑and‑breaking tests; synthetic testing methods are covered in IEC 62271‑101. The consolidated text incorporates Amendment 1 (2024) and recent corrigenda.

Scope

Specifies ratings, performance requirements and direct testing procedures for alternating‑current three‑phase circuit‑breakers intended for use on systems above 1 000 V (50/60 Hz), for both indoor and outdoor installations. The document covers electrical and mechanical characteristics, type and routine tests (making‑and‑breaking tests by direct methods), guidance on dielectric and thermal tests, and requirements for auxiliary and control circuits. For synthetic testing methods and additional guidance, see related parts in the IEC 62271 series.

Key topics and requirements

• Rated voltages, currents and frequency classes for three‑phase AC circuit‑breakers.
• Type, routine and special tests — making and breaking tests by direct methods.
• Dielectric and impulse withstand requirements and test procedures.
• Temperature‑rise, thermal stability and continuous current ratings.
• Mechanical operation, endurance tests and contact performance.
• Requirements for auxiliary circuits, control gear and interlocking.
• Marking, documentation and information to be supplied by the manufacturer.
• Incorporation of amendments and corrigenda clarifying definitions and subclause structure (2024 updates).

Typical use and users

Used by manufacturers of high‑voltage circuit‑breakers, test laboratories, utilities, system integrators, engineering consultants and standards committees involved in specification, type‑testing, procurement and conformity assessment of high‑voltage switching equipment. It is also referenced by design engineers preparing technical specifications and by certification bodies assessing compliance.
