The 10 kA breaking capacity per EN 60898 and IEC 60947-2 means it can safely interrupt a fault current up to 10,000 A — enough for most commercial and light-industrial distribution boards. The built-in residual-current element is Type A, 30 mA sensitivity, so it detects both sinusoidal AC ground faults and pulsating DC fault currents — typical for electronics-heavy circuits (switched-mode PSUs, VFDs, LED drivers) where pure AC-only RCDs may not trip. The 18 mm width (1 MW) means it occupies one slot — tight for retrofit panels where space is already allocated. Supply can come from top or bottom, and the solid neutral is switched internally (1P+N). IP20 rated with conductors connected. Installation depth is 70 mm; total depth is 77 mm.","metaTitle":"Siemens 5SU9304-7PK32 SENTRON RCBO, 32 A, 10 kA, Type A, 30","metaDescription":"Siemens SENTRON 5SU9304-7PK32 RCBO, 1P+N, 32 A, 10 kA breaking capacity, Type A, 30 mA, C-curve, 230/240 V AC, 50/60 Hz.
