The Siemens 5SV3314-6KL is a 2-pole residual current circuit breaker (RCCB) from the SENTRON family, designed for 230 V AC single-phase networks. The 10 kA short-circuit current rating (SCCR) per IEC 61008-1 means the device can withstand and interrupt fault currents up to that level without external series fusing, though a maximum permissible series fuse of 63 A is specified for backup protection if needed.
Snaps onto a 35 mm DIN rail (REG) and occupies 2 modular width units (36 mm wide). The 70 mm depth and 90 mm height are standard for SENTRON modular devices, so it fits existing distribution board layouts with 60 mm grid spacing. Mounting position is unrestricted. IP20 rated with conductors connected — suitable for enclosed distribution boards. The silicon-free construction is noted for environments where silicone outgassing can contaminate contacts or optics.
