SENTRON 5SQ2670-0KA25 — 4-pole MCB, C-curve 25 A, 3 kA
The SENTRON 5SQ2670-0KA25 is a 4-pole miniature circuit breaker (3P+N) rated 25 A with a C tripping characteristic, designed for 400 V AC 50 Hz supply. Overvoltage category 3 and energy limiting class 3 place it in standard final-circuit duty.
At 55 mm installation depth and 3 width units (roughly 54 mm on a standard DIN rail), this breaker occupies a compact slot in the distribution board. IP20 finger-safe terminals are standard for enclosed gear; no washdown rating here, so keep it behind a cabinet door.
