The ABB S803S-C80 is a 3-pole 80 A miniature circuit breaker with a C trip curve, rated for 230/400 VAC and a 50 kA interrupting capacity. It snaps onto a DIN rail for panel integration — the 50 kA rating means it can safely clear a high-fault bolted short without upstream devices needing to coordinate, which simplifies panel design in high-capacity distribution boards.
