The Siemens SENTRON 5SV5314-0 is a 2-pole Type AC residual current circuit breaker (RCCB) rated 40 A with 30 mA trip sensitivity, designed for 230 V AC 50 Hz systems.
In a panel with a 6 kA prospective fault current at the bus, this device coordinates — no need for a current-limiting upstream breaker unless the fault level exceeds that figure. The 30 mA residual sensitivity is the standard threshold for personnel protection in most national wiring rules (IEC 60364, UK BS 7671, etc.). The IP20 rating applies only when the distribution board is installed and conductors are connected; outside the enclosure the terminals are not touch-safe, so it must live inside a locked or tool-accessible panel.
Panel integration
Silicon-free construction is confirmed — relevant for potting or conformal-coating processes where silicone contamination must be avoided.
