The 50 kA interrupting capacity at 230 V AC handles high-fault panels. DIN rail mount, single module width. Snaps into any standard 35 mm DIN rail enclosure. The 1-pole form factor means it protects one phase — use three for three-phase motor circuits or combine with a 3-pole base for grouped protection.","metaTitle":"ABB S801S-K40 MCB 1P K 40A, 50 kA Interrupt Rating","metaDescription":"ABB S801S-K40 MCB, 1 pole, Trip Curve K, 40 A, 230 V AC, 50 kA interrupting capacity.
