The Siemens 5SU1153-7KV10 is a combined residual-current and miniature circuit breaker (RCBO) — an FI/LS protector in Siemens' own naming. It packs a Type A RCD (10 mA sensitivity) and a C-curve MCB (10 A rated current) into a single 1+N-pole, 70 mm wide module. Type A detection means it catches both sinusoidal AC and pulsating DC residual currents — the standard for circuits with single-phase electronics or rectified loads.
