The 70 mm depth fits standard DIN-rail enclosures; the pigtail means the neutral conductor is factory-attached, saving a wiring step at panel build. Type AC detection means it trips on sinusoidal AC residual currents only — fine for resistive and inductive loads like heaters, contactors, and lighting, but not for pulsating DC or mixed-frequency faults from VFDs or switched-mode supplies. The 30 mA sensitivity is standard for personnel protection (shock risk) per IEC 60364.","metaTitle":"Siemens 5SU1356-1DA16 FI/LS Protector, 30mA, 6kA, 16A C-curv","metaDescription":"Siemens 5SU1356-1DA16 FI/LS protector, Type AC, 30mA, 6kA, 1+N-pole, 16A C-curve, pigtail.
