IEC 60947-5-1:2024
Low-voltage switchgear and controlgear - Part 5-1: Control circuit devices and switching elements - Electromechanical control circuit devices
Abstract
IEC 60947-5-1:2024 applies to control circuit devices and switching elements intended for controlling, signalling, interlocking, etc., of switchgear and controlgear.
It applies to control circuit devices having a rated voltage not exceeding 1 000 V AC (at a frequency not exceeding 1 000 Hz) or 600 V DC.
This fifth edition cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) update of the scope structure and exclusions;
b) requirements for control circuits;
c) update of the normal service conditions (e.g. shock and vibration);
d) update of information and marking requirements including environmental information requirements referencing IEC TS 63058:2021;
e) update of the constructional requirements and the corresponding tests considering safety aspects (e.g. artificial optical radiation, security aspects, limited energy source, stored charge energy circuit);
f) update of the EMC requirements according to the generic documents;
g) new requirements for reed contact magnetic switches in Annex D;
h) requirements for class II circuit devices achieved by double or reinforced insulation in Annex F;
i) update of pull-out tests in Annex G;
j) information requirements for audible signalling device in Annex J;
k) insertion of new Annex O.
