The Siemens 5SU1653-1KL25 is an RCBO — a combined residual-current circuit breaker with overcurrent protection — rated at 25 A, 230 V AC, with a 300 mA Type AC residual-current trip and a 4.5 kA breaking capacity. The C-characteristic curve handles moderate inrush from motor or lighting loads without nuisance tripping. The 1P+N form factor (single-pole switched, neutral solid) and N-left wiring orientation match standard domestic and light-commercial distribution boards.
