It carries a B-curve 6A overcurrent trip and a 30 mA Type A residual current detection, rated for a 4.5 kA short-circuit breaking capacity. The Type A designation means it detects pulsating DC fault currents as well as sinusoidal AC, which covers modern electronic loads like switched-mode power supplies and variable-speed drives that can produce smooth DC leakage. The 6A B-curve overcurrent characteristic trips between 3 and 5 times rated current (18–30 A), suited for protecting final circuits supplying lighting, socket outlets, or small control loads. The 30 mA residual sensitivity provides personal protection against direct contact, while the Type A form catches the rectified fault currents that a standard AC-only RCD would miss. ## Panel integration The 70 mm depth (D=70mm) fits standard DIN-rail enclosures and distribution boards without protruding past the cover. The 1+N-pole format occupies a single module width on the rail, with the switched neutral integrated into the same housing — no separate neutral bar connection needed downstream of the device.","metaTitle":"Siemens 5SU1353-6KV06 FI/LS RCBO Type A, 6A, 30mA, 4.5kA","metaDescription":"Siemens 5SU1353-6KV06 FI/LS-protector Type A (PSE/SSF), 6A B-curve, 30mA, 4.5kA, 1+N-pole.
