Power-dependent data, PM330

Note
Recommended connection cross-sections
The recommended connection cross-sections are determined for copper cables at 40 °C
(104 °F) ambient temperature and cables with a permitted operating temperature on the
conductor for 70 °C (laying type C - factor for bundling 0.75 considered) according to
DIN VDE 0298-4/08.03).
Protective conductor cross-section (S: Cross-section of the supply connection phase
conductor, MS: Cross-section of the external protective conductor):
Minimum cross-sections:
• S ≤ 16 mm² -> MS = S
• 16 mm²≤ S ≤ 35 mm² -> MS = 16 mm²
• S > 35 mm² -> MS = 0.5 x S
Recommended cross-sections:
• MS ≥ S
