It accepts AC or DC supply voltage and occupies a single width unit on a DIN rail, with an IP20 finger-safe enclosure. ## How it fits in a panel Snap-on DIN-rail mount, 55 mm installation depth, one width unit (roughly 18 mm). IP20 rated for enclosed panel use — no washdown rating, so keep it behind a gland plate or cabinet door. Overvoltage category 3 and energy limiting class 3, which means it coordinates well downstream of a higher-rated upstream breaker for selective coordination in a distribution board.","metaTitle":"SENTRON 5SQ2170-0KA16 MCB, 1-pole, C-curve, 16 A, 3 kA","metaDescription":"SENTRON 5SQ2170-0KA16 miniature circuit breaker, 1-pole, C-curve, 16 A, 3 kA breaking capacity per EN 60898.
