How to select the iCT contactor rating for different types of lamps

Please find attached the table which shows the maximum number of light fittings for each contactor according to the type, power and configuration of a given lamp.

Please note that :
1-These values are given for a 230 V circuit with 2 active conductors (single-phase
phase/neutral or two-phase phase/phase). For 110 V circuits, divide the values in the table by 2.
2-To obtain the equivalent values for the entire 230 V three-phase circuit, multiply
the number of lamps and the maximum power output:
-byV3 (1.73) for circuits with 230 V between phases without neutral;
-by V3 for circuits with 230 V between phase and neutral or 400 V between phases.
