IEC 61641 PDF

Introduction Assemblies that are correctly operated, properly maintained, well designed and verified in accordance with the IEC series very rarely incur an internal arcing fault in service. However, as fault levels increase, the potential consequences when such a fault occurs become more severe. This, together with the ongoing pursuit for ever greater safety, is bringing internal arcing faults within assemblies to the fore. The factors to be considered are varied and at times very subjective. In addition, a skill in assessing risks is necessary. MODUTEC seeks to share this guide to assist users of low-voltage assemblies in making the right choice in respect of an internal arc fault capability for their application.

Mining and Metals Transportation Our commitment to ensuring the highest levels of operational safety and reliability is evident in all aspects of the Type LV Switchgear design. Modular design permits the simplest and safest reconfiguration on site Single front construction or back-to-back construction Front and rear access Rear access internal and external cable boxes Variable width wire-way up to mm Incoming arrangements available utilizing ACB, MCCB, Isolator, Fuseswitch, Direct Cable or Busduct Combination of fixed and withdrawable units within the same cubicle Main busbars available in ratings from A to A are installed in a fully segregated press-formed horizontal busbar chamber eliminating the possibility of internal contamination. Riser busbars are housed in a completely segregated and insulated press-formed sheet steel enclosure. The riser busbars have been independently tested and certified to withstand a prospective short circuit current of kA for 1 second, kA peak. The integrity of the riser busbar chamber design is further enhanced by the addition of a padlockable horizontal sliding shutter assembly providing a degree of protection of IP4X.
