It packs Type A earth-leakage detection (30 mA trip threshold) and a C-curve overcurrent characteristic (20 A rated current) into a single 1+N-pole module. That means one DIN-rail unit handles both shock protection and branch-circuit overcurrent in residential or light commercial final subcircuits. The 30 mA IΔn is the standard touch-protection threshold; Type A detection covers sinusoidal AC and pulsating DC residual currents (common from single-phase rectifiers in appliances and LED drivers).","metaTitle":"Siemens 5SU1354-7KV20 FI/LS Protector, Type A, 30mA, 10kA, C","metaDescription":"Siemens 5SU1354-7KV20 FI/LS protector, Type A (PSE/SSF), 30mA, 10kA, 1+N-pole C 20A.
