AS 3947.3 SUPP 1-1995

Specifies requirements for fuse-switch-disconnectors and switch-disconnectors for use with low-voltage aerial bundled cable systems in distribution circuits with a rated voltage of 415 V a.c. It is aligned as close as possible to AS 3947.1 and based on AS 3947.3.

This Standard applies to single-pole and three-pole fuse-switch-disconnectors and switch-disconnectors of the integral enclosure type for outdoor use with aerial bundled cable (ABC) having aluminium conductors in distribution circuits with a rated voltage of 415 V a.c. It is applicable to devices with characteristics as stated in Tables A, B, and C which will accept fuse-links/solid-links in accordance with Table D.1.2 Object Sub-clause 1.2 of Part 3 applies.1.3 Referenced documents The following Standards are referred to in this Standard:AS1939 Degrees of protection provided by enclosures for electrical equipment (IP Code)2005 Low voltage fuses -Fuses with enclosed fuse-links2005.21 Supplementary requirements for fuses for use by authorized persons (Fuses mainly for industrial application)- Standardized fuse systems 2005.21.1 Part 1: Fuses with fuse-links with blade contacts2467 Maintenance of electrical switchgear3008 Electrical installations - Selection of cables3008.1 Part 1: Cables for alternating voltages up to and including 0.6/1 kV3560 Electric cables - XLPE insulated- Aerial bundled- For working voltages up to and including 0.6/1 kV3768 Guide to the effects of temperature on electrical equipment3947 Low voltage switchgear and controlgear 3947.1 Part 1: General rules3947.3 Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units1.4 Information to be given with enquiries and orders See Appendix A.
