It breaks fault currents up to 10 kA per EN 60898 and IEC 60947-2, so it handles both overload and earth-leakage protection in a single device, sized for main incomer or large sub-feed duty in a 50 Hz AC panel. The 5SU1344-1KK82 occupies 11 modular width units (198 mm wide) with a 77 mm depth and 90 mm height, mounting in any position. It is designed for distribution-board installation with connected conductors, carrying IP20 protection once enclosed. The neutral conductor is switched internally, and the supply can enter from the top or bottom — no forced orientation.","metaTitle":"Siemens 5SU1344-1KK82 SENTRON RCBO, 4P, 125 A, 30 mA, C","metaDescription":"Siemens SENTRON 5SU1344-1KK82 RCBO, 4-pole, 125 A rated current, 30 mA residual current, C characteristic, 10 kA breaking capacity.
