Part 100: Alternating current circuit-breakers

(IEC 62271-100:2008); German version EN 62271-100:2009
Class/Status: Standard, withdrawn
Released: 2009-12
VDE Art. No.: 0671020


This part of IEC 62271 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V.
It is only applicable to three-pole circuit-breakers for use in three-phase systems and single-pole circuit-breakers for use in single-phase systems. Two-pole circuit-breakers for use in single-phase systems and application at frequencies lower than 50 Hz are subject to agreement between manufacturer and user.
This standard is also applicable to the operating devices of circuit-breakers and to their auxiliary equipment.
Rules for circuit-breakers with an intentional non-simultaneity between the poles are under consideration; circuit-breakers providing single-pole auto-reclosing are within the scope of this standard.
