The ABB S202-C16 is a 2-pole miniature circuit breaker rated 16 A with a C-trip curve, designed for DIN-rail mounting in distribution panels. The 6 kA interrupting rating at 277 VAC means it can safely clear a fault up to that level without welding contacts or cascading upstream — enough for most commercial and light industrial branch circuits. The C-curve (5–10× In magnetic trip) is the standard choice for motor starters, transformers, and capacitor banks where inrush current would nuisance-trip a B-curve breaker.
Panel integration
Snaps onto standard 35 mm DIN rail. The 2-pole width occupies two modular spaces (36 mm). Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded — strip length 8 mm. No backplane power draw; it's a passive thermal-magnetic device.
