How to connect a three-phase difragomat Legrand DX3 4P C40A 30MA-AC?
On the Legrand DX3 4p C40 30mA three-phase difluvomat, there are no contact signs where zero and phases are inserted. Tell me which side is zero?
On some other RCDs or DX3 series diflomats, the letter “N” is indicated on the right terminal, that is, zero is connected to the right terminal. Also in products of other manufacturers (as far as I know, only the “Schneider” has a zero on the left). In general, above the flag should be a diagram of the machine itself. Where the trip units and the transformer are conventionally designated, terminal assignments can be signed there. If there the terminals are only numbered in numbers, then the one where the trip units will not be drawn (semicircular and square protrusions follow each other) - this is zero. But the releases can be indicated on all terminals.
