The 70 mm width means it occupies two standard 35 mm DIN-rail module slots in the panel, which matters when you're packing a sub-distribution board and every slot counts. The C-curve (6 A) trips magnetically between 5× and 10× rated current — so 30 A to 60 A instantaneous — making it a fit for motor-starter, lighting, or small-transformer circuits where inrush isn't extreme but isn't purely resistive. The 300 mA residual sensitivity (Type A) catches pulsating DC fault currents from single-phase rectifiers (common in washing machines, LED drivers, IT gear) while ignoring the normal leakage of a healthy installation. Type A is the minimum for circuits with electronic loads; Type AC would miss half the fault shapes. If your fault level is higher, you'll need to coordinate upstream with a larger MCB or fuse.","metaTitle":"Siemens 5SU1653-7KV06 FI/LS-Protector Type A, 6A C, 300mA, 4","metaDescription":"Siemens 5SU1653-7KV06 FI/LS-protector Type A, 6A C-curve, 300mA residual, 4.5kA breaking capacity, 1+N-pole.
