This part of IEC 62271, which is a Technical Specification, 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.
Satisfactory service performance of controlled switching systems is influenced by the inherent
performance capabilities of the switching device and by the choice of a suitable controller (relay)
and requires proper integration of these devices. Consequently, practical applications of
controlled switching require a coordinated approach to system integration.
This document addresses the performance capabilities of the switching device and establishes
suitability for controlled switching when applied with an appropriate controller. Type tests are
defined, and guidance is provided to establish the switching device capabilities and parameters
required to facilitate proper system integration, but this document does not address the
performance requirements of the controller. In summary, compliance and testing in accordance
with the requirements and guidance presented herein verify the ability of the switching device
to meet defined switching accuracy requirements only when applied with a suitably specified
controller.
