Rated 32 A at 30 °C ambient, it derates to 26.9 A at 70 °C — a thermal curve worth checking if the RCBO sits in a crowded, warm enclosure. The C-curve characteristic (5–10× In magnetic trip) suits mixed resistive and moderate motor-starting loads common in commercial and light-industrial final circuits. Depth is 72 mm, height 85 mm — fits standard distribution boards with 70 mm installation depth allowance. Surge current withstand is 0.25 kA.","metaTitle":"Siemens 5SU1346-7FP32 SENTRON RCBO, 4P, 32A C-curve, 6kA","metaDescription":"Siemens SENTRON 5SU1346-7FP32 RCBO, 4-pole, 32 A rated, C tripping characteristic, 6 kA breaking capacity per EN 60898.
