Type A sensitivity detects pulsating DC residual currents in addition to sinusoidal AC — relevant for circuits feeding single-phase rectified loads such as washing machines, LED drivers, or EV chargers where Type AC devices would be blind to the fault signature.","metaTitle":"Siemens 5SU1656-6KV25 FI/LS Protector Type A, 25A B-Curve, 3","metaDescription":"Siemens 5SU1656-6KV25 FI/LS protector Type A (PSE/SSF), 1+N-pole B 25A, IΔn 300mA, 6kA.
