The C-curve means the magnetic trip activates at 5 to 10 times rated current — 160 to 320 A for this 32 A unit. The 1P+N configuration switches the line conductor and provides a switched neutral — the neutral pole opens and closes with the line, which is required in some regional wiring codes and simplifies isolation for the downstream circuit.
Where it goes in the panel
Accepts supplementary devices like shunt trips or auxiliary contacts for remote status monitoring. Depth of 76 mm and width of 36 mm — that's a standard two-module footprint. Installation depth of 70 mm leaves clearance behind the DIN rail for wiring.
