The Type AC detection covers sinusoidal AC residual currents — the standard choice for general socket-outlet and lighting circuits where no rectified or smoothed DC fault currents are expected. The B characteristic (10A rated current) trips instantaneously at 3–5× In (30–50A), sized for resistive and moderate inductive loads like lighting, socket circuits, and small appliances — not for motor-starting inrush. The 300mA residual sensitivity is a fire-protection level (not personal shock protection), used on circuits where 30mA nuisance tripping is unacceptable but earth-fault fire risk must be covered, such as fixed lighting or distribution sub-mains. The 4.5kA breaking capacity (IEC 60898) means it clears a short-circuit fault up to 4.5kA at the rated voltage without rupturing; verify the prospective short-circuit current (PSCC) at the installation point stays below this. ## Panel Integration The 70mm depth (D=70mm) matches the Siemens 5SV series RCBO footprint, so it fits existing board layouts without extra enclosure depth. Neutral busbar connection is internal to the module — no separate neutral link required downstream.","metaTitle":"Siemens 5SU1653-0KV10 FI/LS Protector, Type AC 300mA, B 10A","metaDescription":"Siemens 5SU1653-0KV10 FI/LS protector, Type AC, 300mA, 4.5kA, 1+N-POL, B characteristic 10A.
