It combines Type A residual-current detection at 30 mA with a B-curve 6 A overcurrent trip, rated for 6 kA breaking capacity. The 70 mm housing depth fits standard Siemens distribution boards and DIN-rail enclosures. Type A detection means this unit responds to sinusoidal AC residual currents and pulsating DC residual currents — the standard requirement for circuits with single-phase rectifiers, switched-mode power supplies, or electronic loads. The 30 mA sensitivity covers personnel protection (indirect contact) per IEC 60364.","metaTitle":"Siemens 5SU1356-6KV06 FI/LS Protector Type A, 6A B-Curve, 30","metaDescription":"Siemens 5SU1356-6KV06 FI/LS protector Type A (PSE/SSF), 30mA, 6kA, 1+N-pole B 6A.
