SENTRON 5SU1653-1GV16 — RCBO, 16 A C-curve, 1P+N
Breaking capacity is 4.5 kA per EN 60898 for domestic-type installations and 15 kA per IEC 60947-2 for industrial panel duty — the higher figure gives you selectivity headroom downstream of a larger upstream MCCB.
Temperature derating and panel fit
The 16 A rating holds only at 30 °C ambient inside the enclosure. At 40 °C it derates to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A — the full curve is on the nameplate. IP20 applies only once the distribution board is closed and conductors are connected; the front face is touch-safe, but the terminals are not during wiring.
Construction and compliance
The 5SU1653-1GV16 is halogen-free and silicon-free.
