Type A residual detection catches pulsating DC fault currents from electronics and single-phase rectified loads — the most common leakage waveform in modern panels. Rated 125 A at 30 °C, the 5SU1624-7WK82 derates to 115.62 A at 40 °C, 111.25 A at 45 °C, 106.25 A at 50 °C, 101.25 A at 55 °C, and 96.25 A at 60 °C. In a sealed distribution board or high-ambient enclosure, the 40 °C figure is the practical design limit — plan your load accordingly. The unit occupies 7 modular width units (198 mm wide) with a depth of 77 mm and installation depth of 70 mm.","metaTitle":"Siemens SENTRON 5SU1624-7WK82 RCBO, 2P, 125 A, C-curve, 300","metaDescription":"Siemens SENTRON 5SU1624-7WK82 selective RCBO, 2-pole, 125 A rated, C-curve, 300 mA Type A residual current, 10 kA breaking capacity.
