Its 10 kA interrupting capacity at 120 VAC ensures it can safely clear a hard fault without upstream coordination issues in a standard distribution panel. The 1-pole footprint leaves room for additional poles or auxiliary contacts in the same row.","metaTitle":"ABB S803UE-K20 MCB, 1P, 13A, Curve C, 10kA, DIN Rail","metaDescription":"ABB S803UE-K20 miniature circuit breaker, 1-pole, 13 A, Trip Curve C, 10 kA interrupting capacity at 120 VAC.
