The Siemens 5SV3316-6KK12 is a 2-pole residual current circuit breaker (RCCB) from the SENTRON family, rated 63 A with a 30 mA trip threshold, Type A waveform sensitivity, and a 230 V AC supply. This is the SIGRES variant, meaning it is designed for harsh ambient conditions — condensation, humidity, or corrosive atmospheres where a standard RCCB would nuisance-trip or degrade.
Installation depth is 70 mm, matching the standard SENTRON RCCB footprint. The IP20 rating applies only when the distribution board is installed with connected conductors — this is a panel-interior device, not a standalone outdoor unit. Grid spacing of 60 mm aligns with standard European enclosure cutouts.
The 30 mA sensitivity is the standard threshold for personnel protection in residential and commercial final circuits — it catches leakage currents that could pass through a human body.
