It is configured as a 1+N-pole unit with a B-curve overcurrent characteristic rated at 40A, designed for 1MW systems. This is a current-production part, actively available through supply channels. The B-curve (3-5 In) trips instantaneously on moderate overloads, making it a good match for resistive and general-purpose loads like lighting, socket outlets, and small appliances — not for motor starting or transformer inrush, which would nuisance-trip on a B-curve. ## Deployment context The 1+N-pole format (switched phase plus switched neutral) is common in single-phase final circuits where the neutral is also disconnected for isolation. The Type AC designation means it detects sinusoidal AC residual currents only — not pulsed DC or smooth DC, so it is unsuitable for circuits with variable-speed drives, LED drivers, or EV chargers that generate pulsating DC leakage.","metaTitle":"Siemens 5SU9306-0DV40 RCCB, Type AC, 30mA, 6kA, 40A B-curve","metaDescription":"Siemens 5SU9306-0DV40 residual current device, Type AC, 30mA trip, 6kA breaking capacity, 1+N-pole B-curve 40A.
