    Abstract - (Show below) - (Hide below)

    Applies to a.c. circuit-breakers designed for indoor and outdoor service for operation on systems with frequencies up to 60 Hz and voltages higher than 1000 V. Sections are included covering service conditions, definitions, ratings, design and construction, type and routine tests, the selection of circuit-breakers for service, information to be given with enquiries, tenders and orders, transport and storage, erection, maintenance, guide for commissioning tests and quality control during manufacture. Nine appendices giving supplementary information are included.

    Scope - (Show below) - (Hide below)

    This standard applies to a.c. circuit-breakers designed for indoor and outdoor installation and for operation at frequencies up to and including 60 Hz on systems having voltages above 1000 V, and to the operating devices of circuit-breakers and to their auxiliary equipment.It applies only 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 are subject to agreement between purchaser and manufacturer.NOTE: Tests to prove the performance under abnormal conditions should be subject to agreement between manufacturer and user. Such abnormal conditions are, for instance, cases where the voltage is higher than the rated voltage of the circuit-breaker, conditions which may occur due to sudden loss of load on long lines or cables, and over-voltages which may occur when closing onto long unloaded lines or cables.This standard does not apply to the following:(a) Circuit-breakers intended for use on motive power units of electrical traction equipment.(b) Circuit-breakers intended for use with overhead lines which include series capacitors.(c) Starting switches, contactors, tap-switches and similar apparatus.(d) Circuit-breakers with closing mechanisms for dependent manual operation, because in such cases rated short-circuit making-current cannot be specified and such dependent manual operation may be objectionable because of safety reasons. This standard does not necessarily apply to circuit-breakers for special conditions of service, e.g. those produced by two earth faults one of which occurs on one side of the circuit-breaker and the other on another phase on the other side of the circuit-breaker.
