Type AC means it detects sinusoidal AC earth faults only — no pulsed DC or smooth DC component. That matters: if your downstream loads include VFDs, switched-mode supplies, or single-phase rectifiers, Type AC may nuisance-trip on the DC component; you'd want Type A or B instead. For purely resistive or inductive AC loads without rectification, this is the standard choice. The 2-pole form factor interrupts both line and neutral on a single-phase circuit. At 2.5 TE (about 55 mm), it takes up two-and-a-half 18 mm module spaces on a DIN rail — plan your enclosure fill factor accordingly.","metaTitle":"Siemens 5SM1317-0FD FI-Protector RCD, 80A 30mA Type AC 2-Pol","metaDescription":"Siemens 5SM1317-0FD FI-Protector residual current device, 80A rated, 30mA sensitivity, Type AC, 2-pole, 230V, 55mm wide.
