DESCRIPTION
IEC TS 62271-319:2024
IEC TS 62271-319:2024 is applicable to alternating current circuit-breakers with intentional non-simultaneous pole operation designed for indoor or outdoor installations and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. This document provides additional ratings and type tests to be conducted for this type of circuit-breaker and is intended to be used in conjunction with IEC 62271‑100:2021. Intentional non-simultaneous pole operation can be implemented by mechanical or electrical means and both methods are within the scope of this document.
