Omfang

IEC 60947-10:2026 applies to semiconductor circuit-breakers with a rated voltage up to 1 000 V AC or 1 500 V DC, intended to be installed and operated by instructed or skilled persons.This document covers the following different types:- semiconductor circuit-breakers (SCCBs) having semiconductor switching elements and, for isolation function, mechanical isolation contacts connected in series;- semiconductor hybrid circuit-breakers (SCHCBs) having semiconductor switching elements and mechanical switching elements in parallel and in addition, for isolation function, mechanical isolation contacts connected in series.In this document, where the term "circuit-breaker" only is used, it applies to both types.This document applies regardless of the rated currents, the method of construction or the proposed applications of the circuit-breakers.The object of this document is to state:a) the characteristics of circuit-breakers;b) the conditions with which circuit-breakers shall comply with reference to:1) operation and behaviour in normal service;2) operation and behaviour under specific abnormal circuit conditions (e.g. overload or short-circuit);3) dielectric properties;4) requirements on electromagnetic compatibility;c) tests intended for confirming that these conditions have been met and the methods to be adopted for these tests;d) information to be marked on or given with the circuit-breakers.
