- 适用范围
- This part of IEC 60669 applies to manually operated general purpose switches, for a.c. 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. The rated current is limited to 16 A maximum for switches provided with screwless terminals. NOTE 1 An extension of the scope to switches for rated voltages higher than 440 V is under consideration. The standard also applies to boxes for switches, with the exception of mounting boxes for flush-type switches. NOTE 2 General requirements for boxes for flush-type switches are given in IEC 60670. It also applies to switches such as: – switches incorporating pilot lights; – electromagnetic remote control switches (particular requirements are given in part 2); – switches incorporating a time-delay device (particular requirements are given in part 2); – combinations of switches and other functions (with the exception of switches combined with fuses); – electronic switches (particular requirements are given in part 2); – switches having facilities for the outlet and retention of flexible cables (see annex B). NOTE 3 The minimum length of the flexible cable used with these switches may be governed by National Wiring Rules. Switches complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 °C, but occasionally reaching 35 °C. NOTE 4 Switches complying with this standard are suitable only for incorporation in equipment in such a way and in such a place that it is unlikely that the surrounding ambient temperature exceeds 35 °C. 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 constructions may be required.
