IEC 60669‑1:2017, Clause 1 is applicable except as follows:
Replacement of the first paragraph with the following:
This part of IEC 60669 applies to electromagnetic remote control switches (hereinafter referred to as electromagnetic RCS) with a rated voltage not exceeding 440 V AC and a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For the control circuit, the rated control voltage does not exceed 440 V AC or 220 V DC.
The RCS coil can be either permanently energized or not permanently energized.
Electronic RCS are within the scope of IEC 60669‑2‑1 but not of this document.
RCS including only passive components such as resistors, capacitors, positive temperature coefficient (PTC) and negative temperature coefficient (NTC) components and printed circuit boards are not considered to be electronic RCS.
Electromechanical contactors for household and similar purposes are within the scope of IEC 61095.
