On a 2-pole 240/415 VAC supply, the S802U-K30 handles line-to-line or line-to-neutral faults within its rated breaking capacity. DIN rail mount means it snaps onto standard 35 mm top-hat rail inside the enclosure. The 2-pole form factor occupies two module widths, so factor that into your rail fill and gland-plate planning. No special busbar or adapter needed for the 240/415 VAC feed — standard comb bus or ring-tongue terminals on the line and load lugs.","metaTitle":"S802U-K30 ABB Miniature Breaker, 30A K Trip 2P 240/415VAC","metaDescription":"ABB S802U-K30 miniature circuit breaker, 30 A K-trip curve, 2-pole, 240/415 VAC.
