The ABB S802S-B50 is a 2-pole high-performance miniature circuit breaker rated 50 A with Trip Curve B, meaning it trips between 3 and 5 times rated current — fast enough to protect semiconductor loads and long cable runs where inrush is low. Snaps onto standard DIN rail, so it drops into any panel layout without extra bracketry.
