Its 3 kA breaking capacity per EN 60898 at 400 V AC is the standard domestic and light-commercial fault-interruption rating — adequate for most sub-distribution boards where the prospective short-circuit current stays under that threshold. The neutral conductor is switched (3P+N), so it opens all live conductors on a fault, which is required in some regional wiring codes and for certain load types where an unswitched neutral could leave a circuit energized. Snaps onto DIN rail, occupies 3 width units, with an installation depth of 55 mm — standard for this class of MCB. Rated for overvoltage category 3 and energy limiting class 3, which tells the panel designer it provides the energy-limiting performance expected for final-circuit protection in fixed installations.","metaTitle":"SENTRON 5SQ2670-0KA32 4-Pole MCB, 32A C-Curve, 3kA","metaDescription":"SENTRON 5SQ2670-0KA32 4-pole MCB, 32A rated current, C tripping characteristic, 3kA breaking capacity per EN 60898 at 400V AC.
