The Siemens 5SU1354-7KV06 is a combined residual-current device and miniature circuit breaker — an FI/LS-protector — in a single 1+N-pole module. It pairs a Type A RCD (30 mA rated residual current) with a C-curve MCB rated 6 A, all in a 70 mm-wide housing. The Type A RCD detects pulsating DC fault currents as well as sinusoidal AC — needed on circuits with electronics, rectifiers, or single-phase drives that can generate pulsed DC leakage.
Snap-on DIN-rail mounting for 70 mm-wide modules.
