Approvals and certificates
The standard VDE 0660-500 /-504; EN 60439-1/-3;
IEC 60439-1/ -3 is one of the most important standards for
distribution systems. It stipulates the requirements for the safe
operation of low-voltage switchgear assemblies.
The standard VDE 0660-500; EN 60439-1 distinguishes
between:
• TTA (type-tested switchgear assemblies)
TTA refers to factory-assembled switchgear assemblies that
conform to an established type or system without deviations
likely to significantly influence the performance from the typical
assembly verified to be in accordance with the standard
DIN VDE 0660-500.
• PTTA (partially type-tested switchgear assemblies)
PTTA refers to switchgear assemblies, including factoryassembled,
type-tested and non-type-tested arrangements,
which comply with the relevant test requirements as specified
in DIN VDE 0660-500.
Both versions (TSK and PTSK) are equivalent to each other. They
offer the same level of safety and the same high standard of
quality. The difference between TTA and PTTA lies in the scope
and the type of tests performed.
All switchgear assemblies produced with type-tested components
are required to undergo routine tests (according to
Table 7, sections 8.3.1 ... 8.3.4 of the aforementioned regulations).
These switchgear assemblies are then TTA-approved.
In the case of switchgear assemblies containing both typetested
and non-type-tested arrangements, proof must be provided
(according to Table 7 of the aforementioned standard) that
the latter are derived (e.g. by calculation) from type tested arrangements
which have complied with the relevant tests. These
switchgear assemblies are then PTTA-approved.
7 Type tests
1. Proof of compliance with the temperature-rise limit
2. Proof of insulation resistance
3. Proof of short-circuit strength
4. Proof of the proper connection between the bodies of the switchgear
assemblies and the protective conductor by monitoring the resistance
measurement
5. Proof of creepage distance and clearance
6. Proof of mechanical functionality
7. Proof of IP degree of protection
3 Routine tests
1. Wiring, electrical functionality
2. Insulation
3. Protective measures
4. Insulation resistance
