It protects a single-phase final subcircuit (1P+N, neutral switched) against both overload/short-circuit and earth leakage. 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.
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.
Mounts in any orientation — the evidence states 'any' mounting position. 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.
Listed as current production — no phase-out notice on record. The 5SU1354-7GV16 is a standard catalog item in the SENTRON range, not a special or end-of-life variant.
