Siemens 5SL4116-8CC — D-curve MCB for high-inrush loads
The Siemens 5SL4116-8CC is a 1-pole miniature circuit breaker from the SENTRON 5SL family, rated 16 A with a D tripping characteristic and a 10 kA breaking capacity per EN 60898 at 230/400 V AC.
Snaps onto DIN rail in any orientation. The 18 mm width (1 width unit) means it occupies one standard module position in a distribution board or enclosure. Terminal capacity accepts 0.75 mm² to 25 mm² conductors. Touch protection is built in.
The D-curve trips between 10 and 20 times the rated current (160–320 A magnetic trip), so it holds through the startup surge of a motor or transformer but clears a hard short quickly. Rated for single-phase operation at 250 V AC and multi-phase at 440 V AC, with a maximum of 60 V DC. The overvoltage category is 3 (distribution level).
