Switches for household and similar fixed-electrical installations - Part 1: General requirements Abstract IEC is also available as IEC RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. This part of IEC applies to manually operated general purpose functional switches, for alternating current AC only with a rated voltage not exceeding V with a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For switches provided with screwless terminals, the rated current is limited to 16 A. This fourth edition cancels and replaces the third edition published in , Amendment and Amendment This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a change of the scope for motor load switches; b deletion of some dated normative references; c changes to the definitions; d in Clause 5 the number of specimens to be used for the tests are clearly given in Table 1 Corresponding Annex A of IEC was therefore deleted ; e in Clause 5 it was clarified on which switches the tests of Clause 19 shall be carried out; f requirements concerning 13 A switches have been included; g mandatory indication that a terminal is suitable for rigid conductor only; h requirements and test conditions for flexible conductors have been included in Clause 12; i requirements for pilot light units have been included; j new test for self-ballasted lamp loads in

This part of IEC applies to manually operated general purpose functional switches, for alternating current AC only with a rated voltage not exceeding V with a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For switches provided with screwless terminals, the rated current is limited to 16 A. Switches covered by this document are, where applicable, intended for the control in normal use of all of the following loads: — a circuit for a tungsten filament lamp load; — a circuit for an externally ballasted lamp load for example LED, CFL, fluorescent lamp load ; — a circuit for a self ballasted lamp load for example LEDi or CFLi ; — a circuit for a substantially resistive load with a power factor not less than 0,95; — a single phase circuit for motor load with a rated current not exceeding 3 A at V VA and 4,5 A at V VA and a power factor not less than 0,6. This applies to both switches rated not less than 10 A that have not undergone additional tests and to momentary switches rated not less than 6 A that have not undergone additional tests.
