What it is and what it does
The ABB S201P-C1.6 is a 1-pole miniature circuit breaker (MCB) rated for 400 V AC, with a C-trip curve at 1.6 A. It protects branch circuits against overload and short-circuit in residential, commercial, and light industrial distribution boards. The C-curve characteristic means it trips at 5–10× rated current, making it suited for loads with moderate inrush — lighting circuits, general-purpose socket outlets, and small transformers.
Voltage and application fit
Rated at 400 V, this MCB fits standard 3-phase distribution panels where single-pole branch protection is needed on a 230/400 V system. The C-curve at 1.6 A handles the inrush from a cluster of LED drivers or a small control transformer without nuisance tripping. Snap-on DIN-rail mounting for enclosure integration.
