The Siemens 5SU1353-1KV13 is an FI/LS combination device — an RCBO that packs residual-current and overcurrent protection into a single 1+N-pole module. The C-curve 13 A thermal-magnetic trip handles inrush from motorized loads like pumps and compressors without nuisance tripping, while the 4.5 kA breaking capacity covers the typical prospective short-circuit current at the sub-distribution board.
