The Siemens 5SU1344-8RC63 is a 4-pole RCBO rated at 63 A with a D tripping characteristic and Type A 30 mA residual current protection. It occupies 7 module widths on a DIN rail, so it fits standard distribution boards with that slot budget. The D curve means it tolerates high inrush currents — think motor or transformer starts — without nuisance tripping, while the 30 mA Type A residual-current element catches sinusoidal AC and pulsed DC fault currents to ground.
