The Siemens SENTRON 5SV4311-0 RCCB is a 2-pole residual current operated circuit breaker designed for reliable protection against electric shock and leakage currents in low-voltage installations. With a rated current of 16 A, Type AC sensitivity, and 30 mA residual current rating, this device ensures dependable personnel and equipment protection in residential, commercial, and infrastructure environments. Engineered as part of the Siemens 5SV4 series, it is built for stability, fast trip response, and compliance with IEC 61008-1 standards.
This RCCB supports a rated operational voltage of 230 V AC at 50 Hz and provides a short-circuit current rating of 10 kA when used with a series fuse up to 63 A. According to Siemens’ specifications, the unit offers a mechanical service life of 10,000 operating cycles, demonstrating robust durability in distribution boards and protective assemblies. The device includes IP20 protection (with connected conductors) and incorporates silicon-free construction for compatibility with sensitive industrial and residential environments.
The Siemens 5SV4311-0 allows installation of supplementary accessories and supports conductor cross-sections up to 35 mm², ensuring secure and flexible wiring. Its compact 2-module width and DIN-rail mounting simplify integration into standardized electrical panels.
