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.
