Product details

The C104MG063 is a thermal-magnetic trip unit from the ComPacT NSX100...250 family, rated 63 A at 40 °C with four fully protected poles (4D). It is designed for generator protection and carries EN/IEC 60947-2 certification, so it coordinates with downstream breakers in a selective distribution panel. The TM-G trip curve provides fixed long-time delay (120–400 s at 1.5× In) and a fixed instantaneous pickup at 125 A — no field adjustment on the magnetic element, which simplifies commissioning for generator feeder circuits.

Ratings and deployment context

IP40 front-face protection keeps tools and fingers out but is not washdown-rated; mount inside a sealed cabinet for wet or dusty areas.
