The 300 mA rated residual tripping current with Type A sensitivity means it detects pulsating DC fault currents on top of sinusoidal AC — the standard choice for circuits feeding single-phase electronics, variable-speed drives, or appliances with rectified inputs. The B tripping characteristic (3–5× In magnetic release) protects lighting and general-purpose final circuits where inrush is moderate. Mounting position is any orientation. The neutral conductor is switched internally (1P+N construction). Supply cable entry can be from top or bottom. IP20 rated with conductors connected and distribution board installed — suitable for enclosed panel use, not exposed washdown areas. Halogen-free and silicon-free construction. Maximum 95% humidity. Energy limitation class 3. Touch protection is fitted. Surge current withstand 1 kA at 8/20 μs waveform. Test equipment minimum voltage 100 V AC.","metaTitle":"Siemens SENTRON 5SU1656-6KK06 RCBO, 6 A, 300 mA, Type A, 2-p","metaDescription":"Siemens SENTRON 5SU1656-6KK06 RCBO, 6 A rated, 300 mA residual current, Type A, characteristic B, 2-pole (1P+N).
