The neutral pole switches, so it isolates both line and neutral on a fault — no separate neutral disconnect needed downstream. Energy limiting class 3 means it clips the let-through energy enough to protect downstream wiring within its rating. Occupies 2 width units (roughly 36 mm) on a standard DIN rail. Installation depth is 55 mm, so it clears most shallow enclosures. Overvoltage category 3 suits fixed-installation distribution boards downstream of the main incoming supply.","metaTitle":"Siemens SENTRON 5SQ3270-1BA16 MCB, 2-Pole C 16A, 3kA","metaDescription":"Siemens SENTRON 5SQ3270-1BA16 miniature circuit breaker, 2-pole (1P+N), C-curve, 16 A, 3 kA per EN 60898, 240 V AC/DC.
