Rated 277 VAC line-to-neutral (or 480Y/277 V wye systems) and carries a 10 kA interrupting rating per IEC 60898 / EN 60898 — that's the standard for household and similar installations, so it's certified for the typical 10 kA prospective fault current you'd see in a North American light-industrial panel fed from a 75 kVA transformer. If you're swapping out a failed breaker in an existing panel, the DIN-rail clip and tunnel terminals (compatible with 1–25 mm² conductor) mean no panel rework — just lever the old unit off, clip the new one on, and torque the terminals.","metaTitle":"ABB S203PR-K30 MCB, 3P, 30A, Curve K, 10kA","metaDescription":"ABB S203PR-K30 miniature circuit breaker, 3-pole, 30 A, Trip Curve K, 277 VAC, 10 kA interrupting rating.
