Functions of internal separation with regard to operator and plant protection
Low-voltage switchgear combinations are classified as type-tested when they comply with the original tested type without any major deviations. Only the consistent implementation of the manufacturing instructions of the producer ensures the compliance with the protection targets and the safety level of the standard.
 
What is internal separation?
Internal separation is achieved by partitions, covers or device encasement. The resulting encased protected spaces are named compartments.
 
What are the benefits of internal separation?
  • Restriction of hazard during connection, maintenance and repair
  • Local limitation of faults and thus quick operational availability
 
Which protective targets can be achieved?
Protection against contact with hazardous parts of adjacent functional units with a degree of protection of at least IPXXB

and / or

protection against the passage of solid foreign objects from one unit of an Assembly to an adjacent unit with a degree of protection of at least IP2X

and

protection against accidental contact of dangerous parts within the functional unit
