The 25 A C-characteristic thermal-magnetic trip handles motor inrush and lighting loads that would nuisance-trip a B-curve; the 30 mA Type A residual-current element catches sinusoidal AC faults plus pulsating DC faults up to 6 mA smooth DC, which covers rectified loads like VFDs, LED drivers, and switched-mode power supplies common in commercial panel builds. Breaking capacity is rated 6 kA at 230 V AC (Icn per IEC 61009-1). If your site study shows higher available fault current, step to the 10 kA variant in the same family. Type A sensitivity (30 mA) is the standard for personnel protection in wet locations and circuits with electronic loads. The 30 mA threshold meets IEC 60364-7-701 for bathroom and outdoor circuits; the Type A waveform recognition ensures it trips on the half-wave rectified faults that Type AC units can miss. No minimum-order restrictions apply for standard quantities. Snap-on DIN-rail mount for EN 60715 (35 mm rail). Single-module width (18 mm per pole) — the 1P+N occupies one module. Torque to 2.0–2.5 Nm.","metaTitle":"Siemens 5SU9356-7CR25 RCBO, 25A C-Curve, 30mA Type A, 6kA","metaDescription":"Siemens 5SU9356-7CR25 RCBO, 1P+N, 25 A, C-characteristic, 30 mA Type A residual current, 6 kA breaking capacity, 230 V AC.
