The D=70 mm dimension refers to the width of the enclosure, fitting standard Siemens distribution boards. The 6 A C-curve overcurrent element protects final circuits supplying resistive and light inductive loads — lighting, small appliances, control transformers — where inrush is moderate. The 300 mA Type AC residual-current element responds to sinusoidal AC fault currents only; it is not suitable for pulsating DC or smooth DC fault conditions (Type A or Type B would be required for drives, UPS, or EV charging circuits). ## Deployment context The 70 mm wide module snaps onto DIN rail inside a Siemens distribution board or similar enclosure. The Type AC residual element means it is intended for general-purpose AC circuits where no electronic loads generate non-sinusoidal fault currents. Common applications include lighting circuits, socket outlets in offices or residential buildings, and small motor circuits with contactor control.","metaTitle":"Siemens 5SU1654-1KV06 FI/LS Protector, 6A C-curve, 300mA, 10","metaDescription":"Siemens 5SU1654-1KV06 FI/LS protector, Type AC, 6A C-curve, 300mA residual, 10kA breaking capacity.
