Technical advice
(*) 3P NG125N connected in a two-pole configuration to reach 125 A (1P / 2P NG125 has a
maximum rating of 80 A).
1 pole isolation solution (1P+N)
Specific use of the iDPN range in a network with one polarity earthed and both
poles isolated: compact solution (1P+N in 18 mm).
2 poles isolation solution (2P)
