It combines Type AC residual current detection at 300 mA with a C-curve overcurrent trip at 10 A, all rated for a 6 kA breaking capacity. The 70 mm depth (D=70mm) fits standard Siemens distribution boards and most DIN-rail enclosures without crowding the gland plate. The 300 mA IΔn (rated residual operating current) is the trip threshold for earth leakage. The C-curve (10 A rated current) trips at 5–10× In for short-circuit protection, typical for lighting, socket outlets, and small motor circuits. ## Deployment context The 1+N-pole format occupies one module width plus neutral, so plan for 2 module-widths per unit in the enclosure layout.","metaTitle":"Siemens 5SU1656-1KV10 FI/LS Protector, Type AC, 10A C, 30mA,","metaDescription":"Siemens 5SU1656-1KV10 FI/LS protector, Type AC, 10A C-curve, 300mA, 6kA, 1+N-pole.
