The 5SU1336-6FP06: 6 A at 30 °C ambient, derated to 5.7 A at 40 °C and 5 A at 60 °C — the thermal curve matters if this lives in a warm enclosure. B curve means magnetic trip between 3 and 5 times In (18–30 A), so it's sized for resistive or lightly inductive loads, not motor starts. 6 kA breaking capacity per EN 60898 covers most domestic and light commercial fault levels. Type A residual detects AC and pulsating DC faults, which is the standard for circuits with electronics or single-phase rectifiers.
Panel fit and installation
Three modular-width units (54 mm wide) on DIN rail. Depth is 72 mm, installation depth 70 mm — check your enclosure depth if you're retrofitting into a shallow gland plate. Mounting position any, supply feed either top or bottom. IP20 with the distribution board installed and conductors connected — not for open-panel washdown areas.
No official successor because none is needed.
