It mounts on a standard DIN rail and carries a 10 kA interrupting rating at 277 VAC — that's the fault current it can safely clear without welding contacts or rupturing the case, sized for typical commercial and light industrial panelboards where the available fault current stays under that threshold. ## DIN-rail fit & panel integration Snaps onto 35 mm DIN rail per EN 60715. Four-pole width means it occupies four modular spaces (4 x 17.5 mm) on the rail — plan the gland plate and fill factor accordingly if you're swapping into an existing panel.","metaTitle":"ABB S204-B10 MCB, 4P B 10A, 480Y/277V, DIN Rail","metaDescription":"ABB S204-B10 miniature circuit breaker, 4-pole, 10 A, trip curve B, 10 kA interrupting rating at 277 VAC.
