IS 3854 : 2023 Switches for Domestic and Similar Purposes - Specification
1 SCOPE
1.1 This standard applies to manually operated general-purpose switches for alternating currents only, with a rated voltage not exceeding 440 V and a rated current not exceeding 63 A, intended for household and similar fixed-electrical installations either indoors or outdoors.
1.2 The rated current is limited to 16 A for switches provided with screw less terminals.
NOTE - The rated current is limited to 16 A for switches-provided with insulation piercing terminals (IPT's) according-to Annex D.
1.3 Switches covered by this document are, where applicable, intended for the control in normal use of all the following loads:
a) A circuit for a tungsten filament lamp load;
b) A circuit for an externally ballasted lamp load (for example LED, CFL, fluorescent lamp load);
c) A circuit for a self-ballasted lamp load (for example LEDi or CFLi);
d) A circuit for a substantially resistive load with a power factor not less than 0.95; and
e) A single phase circuit for motor load with a rated current not exceeding 3 A at 250 V (750 VA) and a power factor not less than 0.8. 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.
1.4 This document also applies to boxes for switches, with the exception of flush mounting boxes for flush-type switches.
NOTE - General requirements for boxes for flush-type switches are given in IS 14772.
1.5 It also applies to switches such as:
a) Switches incorporating pilot lights;
b) Switches incorporating a time-delay device;
c) Combinations of switches and other functions (with the exception of switches combined with fuses); and
d) Switches having facilities for the outlet and retention of flexible cables (see Annex A).
Switches complying with this standard are suitable for use at ambient temperatures not normally exceeding 35 °C, but occasionally reaching 45 °C.
NOTE - Switches complying with this standard are suitable only in corporating in equipment in such a way and in such a place that it is unlikely that the surrounding reaches a temperature exceeding 45 °C.
1.6 In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special construction and/or additional requirements may be required.
1.7 This standard does not apply to circuit breakers for household and similar installations, to switches for appliances, in-line cord switches and switches incorporated in cable reels.
