It integrates Type A earth-leakage detection (300 mA IΔn) with a 10 kA breaking-capacity C‑characteristic 16 A overcurrent trip, all in a 1+N-pole format. Type A means it catches pulsating DC fault currents on top of sinusoidal AC leakage, which matters for modern loads with half-wave rectification (switched-mode supplies, variable-speed drives, washing machines). The C‑curve (5–10× In magnetic trip) handles motor inrush and transformer energization without nuisance tripping. The 70 mm width (4 TE on a standard DIN rail) occupies one full module position in a Siemens distribution board or any 18 mm pitch enclosure. It snaps onto the DIN rail and terminates with the incoming supply on the top busbar and the outgoing circuit on the bottom load terminal. No separate RCD and MCB means one less wiring step and one less DIN slot used — useful when panel fill factor is tight. The 300 mA residual sensitivity is a deliberate choice: it's higher than the 30 mA required for personal shock protection, so this unit is intended for fire protection or equipment protection on circuits where a 30 mA device would nuisance-trip (e.g., long cable runs with natural leakage, or industrial machinery with filtering).","metaTitle":"Siemens 5SU1654-7KV16 FI/LS Protector Type A, 300mA, 10kA, C","metaDescription":"Siemens 5SU1654-7KV16 FI/LS protector Type A (PSE/SSF), 70mm wide, 300mA IΔn, 10kA breaking capacity, 1+N-pole C 16A.
