The Siemens SENTRON 5SV4314-0GV01 is a 2-pole residual current circuit breaker (RCCB), Type AC, rated 40 A at 230 V AC, 50 Hz, with a 30 mA trip sensitivity. This is an instantaneous (non-time-delayed) Type AC design — it responds only to sinusoidal residual currents, not to pulsed DC or mixed-frequency waveforms. If your installation includes variable-speed drives, UPS systems, or LED lighting that can generate smooth DC fault currents, a Type A or Type F RCCB would be the correct choice; this unit is intended for circuits where the fault current is purely sinusoidal AC.
Supply can enter from top or bottom. The IP20 rating applies only when the distribution board is installed and conductors are connected — the front face is finger-safe, but the terminals are not protected against water ingress.
The manufacturer lists this part as Active (current production). No end-of-life notice or last-time-buy date is on record. The bulk packaging variant (36 units per pack) is the standard commercial offering.
