The Siemens 5SU1356-0DV06 is a combined residual current device and miniature circuit breaker — an RCBO, or FI/LS-protector in Siemens terminology. It covers both overcurrent and earth-fault protection in a single 1+N-pole unit, rated 6A B-curve with 30mA trip sensitivity and 6kA breaking capacity. The Type AC designation means it detects sinusoidal AC residual currents only — the most common class for general socket-outlet and lighting circuits where no pulsating DC or smooth DC fault currents are expected. The 30mA sensitivity is the standard for personal protection against direct contact in residential and commercial final circuits.
Deployment context
The 70mm depth (D=70mm) and pig-tail connection make this unit a direct swap for Siemens 5SU1-series RCBOs in standard distribution boards. Mounts on DIN rail in consumer units or sub-distribution panels.
