EN 60947-3:1992

Low-voltage switchgear and controlgear - Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units

This standard applies to switches, disconnectors, switch-disconnectors and fuse-combination units to be used in distribution circuits and motor circuits of which the rated voltage does not exceed 1 000 V a.c. or 1 500 V d.c. The manufacturer shall specify the type, ratings and characteristics according to the relevant standard of any incorporated fuses. This standard does not apply to equipment coming within the scope of EN 60947-2, EN 60947-4-1 and EN 60947-5-1; however, when switches and fuse-combination units coming into the scope of this standard are normally used to start, accelerate and/or stop an individual motor they shall also comply with the additional requirements given in Appendix A. This standard does not include the additional requirements necessary for electrical apparatus for explosive gas atmospheres. Notes 1. Depending on its design, a switch (or disconnector) can be referred to as "a rotary switch (disconnector)", "camoperated switch (disconnector)", "knife-switch (disconnector)", etc. 2. If they are not manually operated, switches and disconnectors may have to comply with additional requirements. 3. In this standard, the word "switch" also applies to the apparatus referred to in French as "commutateurs", intended to modify the connections between several circuits and inter alia to substitute a part of a circuit for another. 4. In general, throughout this standard switches, disconnectors, switch-disconnectors and fuse-combination units will be referred to as "equipment".
