DIN rail mount, so it clips straight into a standard panel enclosure. Snap-on DIN rail mount, standard 35 mm. The S800S frame uses a dedicated busbar system — verify the busbar pitch matches your existing distribution block if you're retrofitting into an older panel. Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded; strip length 8 mm.","metaTitle":"ABB S801S-K50 MCB S800S 1P K 50A, 50 kA","metaDescription":"ABB S801S-K50 MCB, 1-pole, Trip Curve K, 50 A, 230 V AC, 50 kA interrupting rating, DIN rail.
