It provides both overcurrent protection (B-curve, 25 A rated current) and earth leakage protection (Type AC, 30 mA sensitivity) in one DIN-rail mounted unit, with a 6 kA short-circuit breaking capacity. This is the kind of device you'd find on a lighting final circuit or a general-purpose socket outlet in a commercial or residential distribution board — one module, two protection functions, saving a rail position over separate RCD and MCB. The B-curve (25 A) means the magnetic trip operates between 3 and 5 times In (75–125 A), so it's sized for resistive and light inductive loads like lighting or small appliances, not motor starting. ## Integration note The 1+N-pole form factor means it switches and protects the phase conductor only; the neutral is switched internally for isolation but is not overload-protected — that's standard for single-phase RCBOs in TN and TT systems. The D=70 mm dimension refers to the depth behind the panel face, so verify enclosure depth before committing the board layout, especially in shallow consumer units.","metaTitle":"Siemens 5SU9306-0DV25 RCBO, 25A B-Curve, 30mA, 6kA","metaDescription":"Siemens 5SU9306-0DV25 RCBO, Type AC, 25A B-curve, 30mA sensitivity, 6kA breaking capacity.
