The 70 mm module width (4 MW) fits standard DIN-rail distribution boards. Type A detection covers pulsating DC fault currents up to 6 mA smooth DC superimposed — essential for circuits feeding single-phase rectified loads like washing machines, LED drivers, or IT equipment where a pure AC-sensing RCD would be blind. As a Siemens 5SU series device, the 5SU1356-6KV20 is designed and tested to EN 61008 / EN 61009 for residual-current and overcurrent protection. The Type A marking confirms compliance with the harmonic-rich load profiles covered by VDE 0664-10 and IEC 62423. Full declarations of conformity and CE marking documentation are available from Siemens Industry Support; the part also carries the PSE/SSF mark for Japanese-market acceptance.","metaTitle":"Siemens 5SU1356-6KV20 FI/LS-Protector Type A, 20A B-Curve 30","metaDescription":"Siemens 5SU1356-6KV20 FI/LS-Protector Type A (PSE/SSF), 1+N-pole B 20A, 30mA, 6kA.
