What this RCBO is and where it fits
The Siemens 5SU1354-7GV16 is a SENTRON RCBO — a combined residual current device and miniature circuit breaker in a single 2-module-width unit (36 mm). It protects a single-phase final subcircuit (1P+N, neutral switched) against both overload/short-circuit and earth leakage. The C-curve trips between 5× and 10× rated current, so it is sized for inductive loads like small motors, contactor coils, or fluorescent lighting banks where inrush exceeds a B-curve's threshold. Rated 16 A at 30 °C ambient, with a published derating curve down to 12.32 A at 70 °C — important if the RCBO shares a crowded enclosure with other heat sources.
Breaking capacity and selectivity
Two SCCR ratings are listed: 10 kA per EN 60898 (the household standard) and 20 kA per IEC 60947-2 (the industrial standard). In practice, the 20 kA figure governs when the RCBO is installed in an industrial panel with a higher prospective fault current. The 10 kA rating is the limit for residential or light-commercial boards. The 4 000 V surge voltage resistance (impulse withstand) and overvoltage category III rating confirm it is suitable for fixed-installation distribution boards, not just plug-in portable equipment.
Mounting and environmental constraints
Mounts in any orientation — the evidence states 'any' mounting position. The 70 mm installation depth fits standard domestic and light-industrial distribution boards. IP20 only when installed with connected conductors, so the RCBO itself is not rated for wet or dusty environments; the enclosure must provide the environmental seal. Halogen-free and silicon-free construction matters for clean-room or high-reliability installations where outgassing from a fault event must be minimized.
Lifecycle and sourcing
Listed as current production — no phase-out notice on record. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time. The 5SU1354-7GV16 is a standard catalog item in the SENTRON range, not a special or end-of-life variant.
