LED lamps - choice of contactors
From Electrical Installation Guide
Figure N49 and Figure N50 show the maximum number of LED lamps for each contactor / relay.
- 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.
- To obtain the equivalent values for the whole of a 230 V three-phase circuit, multiply the number of lamps and the total acceptable power:
- by √3 (1.73) for circuits with 230 V between phases without neutral,
- by 3 for circuits with 230 V between phase and neutral or 400 V between phases.
- for Reflex iC60:
- B-curve ratings, the number of lamps should be reduced by 50 %.
- D-curve ratings, the number of lamps should be increased by 50 %.
