03 · Selection points
Four practical selection points.
Choose by circuit function, conductors and documented electrical limits.
- 01
Pole arrangement
Four protected poles in the MV/MW family catalogue. The example switches L1, L2, L3 and N; PE stays separate.
- 02
Current and protection function
Curve B: match starting currents and conductor protection to the 40 A rating. Ambient temperature affects the available continuous current; use the Hager derating table.
- 03
Voltage and fault capacity
Icn 3 kA follows IEC 60898-1. The exact current record has no separate voltage-specific capacity table; do not infer higher capacities or an Icu value.
- 04
Mounting and connections
DIN-rail mounting, 4 modules / 70 mm wide. Follow the manufacturer's terminals and installation instructions. Nominal terminal torque: 2.8 Nm.
