The 40 A rating and Curve D mean it handles high inrush loads — motor starting, transformer energization, welding equipment — without nuisance tripping, while still clearing faults. The 50 kA interrupting rating at 230 VAC gives it enough breaking capacity to sit upstream of sub-panels or directly at the service entrance in most commercial and light industrial installations, without needing a current-limiting fuse ahead of it.","metaTitle":"S802S-D40 ABB 40A 2-Pole Trip Curve D MCB, 230V, 50kA","metaDescription":"ABB S802S-D40 miniature circuit breaker, 40A, 2-pole, Trip Curve D, 230 VAC, 50 kA interrupting rating.
