That's a straight line you can interpolate; for a 40 °C panel the effective capacity is 30.4 A, so a 32 A continuous load won't hold. That's appropriate for circuits with a modest inrush — think a few fluorescent fittings, small pumps, or a domestic refrigerator. For highly inductive loads like a large motor start, a D-curve would be a better fit; this isn't that part. Insulation voltage (Ui) is 264 V, surge voltage resistance 4 000 V, overvoltage category III, pollution degree 2 — standard for a distribution board downstream of the main switch. IP20 with conductors connected. Mounting position any — no restriction on upright or horizontal. Halogen-free and silicon-free construction, so it's fine for clean-room or sensitive-environment panels.","metaTitle":"5SU1354-7KK32 SENTRON RCBO, 32 A, C-curve, 10 kA","metaDescription":"Siemens SENTRON 5SU1354-7KK32 RCBO, 1P+N, 32 A at 30 °C, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.
