The 1.6 A rating sets the continuous current it carries without tripping; the K curve means it tolerates higher inrush currents than a B or C curve — typically 8–12× the rated current before the magnetic trip fires — making it a fit for inductive loads like small transformers, solenoid valves, or motor starters where the startup surge would nuisance-trip a standard curve. Rated at 277 VAC with a 10 kA interrupting capacity, this breaker safely clears a fault up to 10,000 A at that voltage without welding contacts or venting arc plasma into the enclosure. ## Trip Curve K — where it belongs Trip Curve K is the middle ground between the motor-protection Curve C (5–10× In) and the high-inrush Curve Z (2–3× In). It's specified for circuits with moderate inductive surges — think control transformers, relay coils, and small DC power supplies — where a Curve C might nuisance-trip on energization but a Curve D (10–14× In) would delay fault clearing too long for the downstream equipment. The 1.6 A rating on this 2-pole unit covers small branch circuits in automation panels where the load current is under 1.6 A steady-state but the inrush can spike to 12–19 A momentarily.","metaTitle":"S202P-K16 ABB Mini Circuit Breaker, 1.6 A, Curve K, 2-Pole","metaDescription":"ABB S202P-K16 2-pole MCB, 1.6 A, Trip Curve K, 277 VAC, 10 kA interrupting capacity.
