For a panel fed from a transformer or a sub-distribution board with a modest fault level, that's adequate. Overvoltage category 3 means it's rated for fixed-installation use — think permanent wiring in a distribution board, not plug-in gear. The neutral conductor is switched, which is a detail worth noting: on a 2-pole breaker that switches both live and neutral, you get full isolation on the outgoing circuit. That matters for maintenance lockout on a 230 V single-phase line where you want both poles opened.","metaTitle":"Siemens SENTRON 5SQ2270-0KA13 MCB, 2-pole C 13 A, 3 kA","metaDescription":"Siemens SENTRON 5SQ2270-0KA13 miniature circuit breaker, 2-pole, C-curve, 13 A, 3 kA breaking capacity per EN 60898/IEC 60947-2, 400 V AC, 50 Hz.
