IEC 63508 Ed. 1.0 en:2026

Full Description

IEC 63508:2026 The purpose of this document is to describe product classes and properties, representing the miniature circuit-breaker (MCB), to become a part of the IEC 61360-4: IEC Common Data Dictionary (IEC CDD). It includes data required for product selection as well as data required
for engineering.
This document intends, as a contribution to the IEC Common Data Dictionary, to be used by catalogue consortia, other database standards and software as a data reference for circuit-breakers and similar equipment for household use.
NOTE In the future, it is intended to extend the IEC 63508 DB to other types of products e.g. arc fault detection
devices (AFDDs), residual current circuit breakers (RCCBs), residual circuit breaker with overcurrent protection (RCBOs).
