Type F residual current detection handles AC and pulsed DC fault currents, including those from frequency converters and single-phase drives, which a standard AC type would miss.
The compact 1 MW (one module width) design saves panel space — 21 mm wide per the packaging dimensions. The 1-pole+N configuration switches the live conductor and disconnects the neutral, but the neutral is not switched on fault — it is a switched neutral for isolation only. The super-resistant K classification indicates the device is designed for high inrush currents (e.g., from capacitor banks or motor starting) without nuisance tripping.
RoHS compliant since 01-07-18. Export control classification: AL N / ECCN N — no restrictions. Product class B means return is restricted; contact your Siemens partner for return authorization. Active lifecycle — no end-of-life notice.
