The Type A designation detects pulsating DC fault currents superimposed on AC — needed on circuits with single-phase rectifiers, switching power supplies, or modern electronics that produce smooth DC ripple. ## Deployment context The 1+N-pole format (switched phase plus switched neutral) fits standard DIN-rail enclosures — common in European-style consumer units and sub-distribution boards. The 70 mm depth (D=70 mm) is within the typical 85 mm enclosure depth, so no panel-depth conflict. The C-curve (32 A) is sized for motor-starting or transformer inrush loads, not purely resistive circuits; if the load is lighting or heaters, a B-curve would trip faster on small overloads.","metaTitle":"Siemens 5SU1354-7KV32 FI/LS Protector Type A, 30mA, 10kA, C","metaDescription":"Siemens 5SU1354-7KV32 FI/LS-protector Type A (PSE/SSF), 30mA, 10kA, 1+N-pole, C 32A.
