The B-curve 6A rating means it trips magnetically at 3–5× rated current (18–30 A), sized for resistive or lightly inductive loads like lighting or control transformers. The 300 mA residual sensitivity (Type AC, sinusoidal AC only) covers general socket circuits where a 30 mA unit would nuisance-trip on leakage; it's not for personal shock protection — that needs 30 mA or less. The 70 mm width (4 DIN modules) fits a standard DIN-rail enclosure. Snap-on DIN-rail mount for standard 35 mm rail. The 70 mm width (4 modules) means it occupies four adjacent positions in a consumer unit or distribution board. The 1+N-pole configuration switches the line and provides neutral disconnect — verify the neutral bar arrangement in your panel, as some older boards use a solid neutral bus that needs bridging.","metaTitle":"Siemens 5SU1653-0KV06 FI/LS Protector, 6A B-Curve 300mA 4.5k","metaDescription":"Siemens 5SU1653-0KV06 FI/LS protector, Type AC, 6A B-curve, 300mA residual, 4.5kA breaking capacity.
