The 30 mA rating means it protects against lethal shock in standard domestic and commercial final circuits; Type A ensures it catches the pulsed DC residuals from single-phase rectified loads (washing machines, LED drivers, IT equipment) that a Type AC would miss. The B-curve 25 A trips magnetically at 3–5× In (75–125 A) for short-circuit protection of resistive or lightly inductive loads — sized for lighting, socket outlets, or small heater circuits up to 25 A.","metaTitle":"Siemens 5SU1354-6KV25 FI/LS Protector Type A, 30mA, 10kA, B","metaDescription":"Siemens 5SU1354-6KV25 FI/LS protector Type A (PSE/SSF), 30mA, 10kA, 1+N-pole, B-curve 25A.
