12. Technical data
12.1 Enclosure
The individual CUE cabinet sizes are characterised by their
enclosures. The table shows the relationship of enclosure class and
enclosure type. The enclosure can be identified on the basis of
typical shaft power, voltage and IP class.
Example:
Read from the nameplate:
•
Supply voltage = 3 × 380-500 V.
• Typical shaft power = 1.5 kW (2 hp).
• Enclosure class = IP20.
The table shows that the CUE enclosure is A2.
