Type A residual current detection covers pulsating DC fault waveforms from single-phase rectifiers (switched-mode supplies, LED drivers, washing machine electronics), not just sinusoidal AC. The 30 mA sensitivity meets the 30 mA threshold for additional protection against direct contact per IEC 60364. The 1P+N form factor occupies a single modular DIN-rail width (18 mm per pole typical for Siemens 5SU9 series). Neutral switching is integral — the N pole opens and closes with the phase, which avoids a floating neutral on trip. Verify the neutral busbar arrangement in the distribution board: some older boards use a solid N bar that must be broken for this RCBO.","metaTitle":"Siemens 5SU9356-7CR32 RCBO, 6 kA, Type A, 30 mA, C-32 A","metaDescription":"Siemens 5SU9356-7CR32 RCBO, 1P+N, 6 kA breaking capacity, Type A, 30 mA residual current, C-curve 32 A, 230 V AC.
