The 5SJ6116-7: The C-curve (tripping characteristic class C) means the magnetic trip fires at 5–10× In, so 80–160 A instantaneous. The 6 kA breaking capacity (Icn per EN 60898, Icu per IEC 60947-2) is the standard domestic/light-commercial fault level across most of Europe and Asia — adequate for a 230/400 V distribution board with a typical upstream transformer impedance. The 16 A rating at 240 V AC is a common lighting and general-purpose socket circuit size; at 60 V DC the same pole handles up to 16 A, useful for small DC control circuits. Rated insulation voltage is 440 V AC, and the maximum operational voltage with multi-phase connection is also 440 V AC — so this single-pole breaker can be ganged with others for 3-phase 400 V line-to-neutral protection. The overvoltage category 3 and pollution degree 2 ratings confirm it is designed for fixed-installation distribution boards, not portable equipment.
This is a standard catalog line from the SENTRON 5SJ6 family, widely stocked across distribution.
Environmental and handling notes
Operating ambient is periodically +55 °C at up to 95% humidity — fine for most indoor industrial environments. The breaker can be sealed (tamper-evident sealable) and accepts any supply-side connection position. Vibration resistance is tested to 50 m/s² at 25–150 Hz and 60 m/s² at 10–150 Hz per IEC 60068-2-6, so it holds up on a machine-mounted sub-panel.
