The 70 mm depth fits standard DIN-rail distribution boards. Type A detection covers both sinusoidal AC residual currents and pulsating DC — the common waveform from rectifiers, switched-mode supplies, and variable-speed drives. The C-curve 25 A overcurrent characteristic handles motor-starting inrush and moderate inductive loads without nuisance tripping. ## Deployment context Snap-on DIN-rail mounting for panel integration. The 1+N-pole format (switched phase, switched neutral) is common in single-phase final circuits where neutral isolation is required.","metaTitle":"Siemens 5SU1356-7KV25 FI/LS Protector Type A, 30 mA, 6 kA, C","metaDescription":"Siemens 5SU1356-7KV25 FI/LS-protector Type A (PSE/SSF), 30 mA, 6 kA, 1+N-pole C 25 A.
