The ABB S801S-C20 is a 1-pole miniature circuit breaker from the S800S series, rated 20 A with Trip Curve C at 230 VAC. Its 50 kA interrupting rating means it can safely clear a fault up to that level at rated voltage — important for high-fault-capacity panels where a lower-rated breaker would need upstream current-limiting fuses or a larger main breaker to coordinate.
Panel fit and deployment
Snaps onto standard DIN rail — no tools needed for mounting, which speeds panel assembly. The single-pole format occupies one module width, leaving room for adjacent breakers or accessories in the same rail row.
