Further information about planning7.1 Dimensioning and selection7.1.4 Degrees of protection for busbar trunking systemsUse in areas at risk of fireIn areas at risk of fire, in accordance with European standard HD 384.4.482 S1, increasedrequirements are placed on the degree of protection to be afforded for electrical equipment.In the event of a fire risk due to the nature of the materials being processed or stored, if it ispossible that dust will accumulate, the minimum degree of protection must be equivalent toIP5X. If dust is not to be reckoned with, national regulations shall apply accordingly.The risk prevention arm of the association of German insurers sets out the followingrequirements:– In the event of a fire risk due to dust or/and fibres: IP5X degree of protection– In the event of a fire risk due to other readily flammable solid foreign bodies with adiameter of 1 mm or more: IP4X degree of protectionSIVACON 8PS busbar trunking systems meet these requirements. They are thereforesuitable for such applications.7.1.5 Degrees of protection for electrical equipment (DIN EN 60529)1. code digit 2. code digitProtection against direct Protection against solid foreign Protection against ingress of liquidcontactbodies and dustIP00 No special protection No special protection No special protectionIP20 Against finger contact Against solid bodies ≥ 12.5 mm No special protectionIP34 Against tools Against solid bodies ≥ 2.5 mm No damage caused by splashwaterIP41 Against foreign objects Against solid bodies ≥ 1 mm No damage caused by vertically dripping water(Vertical drops)IP43 Against foreign objects Against solid bodies ≥ 1 mm Protected against damage caused by water sprayIP54 Against foreign objects Against hazardous dust deposits No damage caused by splashwaterinside (Dust-tight)IP55 Against foreign objects Against hazardous dust deposits No damage caused by hosewaterinside (Dust-tight)IP65 Against foreign objects Against penetration of dust(Dust-tight)No damage caused by hosewaterIP66 Against foreign objects Against penetration of dust(Dust-tight)IP67 Against foreign objects Against penetration of dust(Dust-tight)IP68 Against foreign objects Against penetration of dust(Dust-tight)In the event of temporary immersion, ingress ofwater will have no harmful effects (Water jet)Water may not ingress in harmful quantitiesduring immersion (Temporary immersion)Water may not ingress in harmful quantitiesduring immersion for indefinite periods(Continuous immersion)Planning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 239
