It pairs Type AC earth-leakage detection at 30 mA with a B-curve overcurrent trip at 16 A, all in a single 1+N-pole module rated for 6 kA breaking capacity. The pig-tail neutral connection simplifies wiring in distribution boards where the neutral bar is already landed. The 30 mA residual-current threshold is the standard for personal shock protection in residential and commercial final circuits — it catches leakage through a person touching a live conductor. The B-curve 16 A overcurrent trip handles general-purpose socket outlets and lighting circuits where inrush is moderate. The 1+N-pole format switches the line and disconnects the neutral in a single module, saving a DIN-rail width compared to separate RCD and MCB.","metaTitle":"Siemens 5SU1356-0DA16 FI/LS Protector, Type AC, 16A, 30mA, 6","metaDescription":"Siemens 5SU1356-0DA16 FI/LS-protector, Type AC, 30mA, 6kA, 1+N-pole, B-curve 16A, pig-tail.
