The single phase supply voltage must be wired to terminal 1L1 and 3L2 for proper single phase operation.
In applications switching two single phase loads (R1 and R2) where the combined load current exceeds
the contactor’s rating (40 or 50 Amps) the return/neutral lead must not be wired through the contactor
(see above drawing).
