The Type A designation means it detects sinusoidal AC residual currents and pulsating DC residual currents up to 6 mA of smooth DC — the standard for general socket-outlet circuits and equipment with rectifiers or switching power supplies. ## Panel Integration Note At 2TE (36mm) width and 55mm depth, the 5SM1311-6BA fits standard DIN-rail enclosures. The Type A characteristic covers most mixed-load final circuits with electronic loads (PCs, LED drivers, appliances with half-wave rectification). For circuits with frequency converters or EV chargers, a Type F or Type B RCD would be required — this Type A is not rated for those higher DC components.","metaTitle":"Siemens 5SM1311-6BA FI Protector Type A, 16A 30mA 2-Pole","metaDescription":"Siemens 5SM1311-6BA FI Protector Type A (PSE/SSF), 16A 2-pole, 30mA residual current, 230V, 2TE.
