The Siemens 5SY4216-8CV is a 2-pole miniature circuit breaker (MCB) with a D16 tripping curve and a rated short-circuit breaking capacity Icu of 15 kA at 400 V AC. That 15 kA rating means it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream — a solid spec for sub-distribution boards where the prospective short-circuit current is high.
