It packs Type A residual current detection (sensitive to pulsating DC and AC fault currents) with overcurrent protection in a single 1+N-pole module. The 300 mA IΔn rating means it trips on ground faults above that threshold, which is typical for sub-distribution or circuits feeding equipment where a 30 mA device would nuisance-trip. The B-curve 16 A overcurrent characteristic clears short-circuit faults between 3× and 5× rated current (48–80 A), and the 10 kA breaking capacity at 400 V AC means it can safely interrupt fault currents up to that level without upstream damage — sized for residential or light commercial final circuits where the prospective short-circuit current stays under 10 kA. ## Deployment context and panel fit Snap-on DIN rail mounting for 70 mm deep enclosures. The 1+N-pole format occupies a single module width, so it fits standard consumer unit or sub-distribution board layouts. Type A detection covers modern electronics loads (washing machines, LED drivers, EV chargers) that generate pulsating DC fault currents — a standard AC-only RCD would miss those. The 10 kA SCCR at 400 V matches typical domestic and light commercial installation conditions per IEC 60947-2 and EN 60898.","metaTitle":"Siemens 5SU1654-6KV16 FI/LS Protector Type A, 16A B-Curve, 3","metaDescription":"Siemens 5SU1654-6KV16 FI/LS protector Type A (PSE/SSF), 1+N-pole B 16A, 300mA IΔn, 10kA breaking capacity.
