Its 3 kA breaking capacity per EN 60898 covers standard residential and light commercial branch-circuit fault levels — adequate for most final subcircuits where the prospective short-circuit current stays under that threshold. The C-curve (5–10× In magnetic trip) suits inductive loads like small motor starters and lighting banks where inrush could nuisance-trip a B-curve device.","metaTitle":"Siemens SENTRON 5SQ2370-2YA50 MCB, 3P C 50A, 3kA","metaDescription":"Siemens SENTRON 5SQ2370-2YA50 miniature circuit breaker, 3-pole, C-curve, 50 A, 400 V AC, 3 kA breaking capacity per EN 60898.
