The Siemens 5SY4214-7CV is a 2-pole miniature circuit breaker with a C-trip curve and a rated current of 0.3 A. Its 15 kA ultimate breaking capacity (Icu) at 400 V AC means it can safely interrupt a fault current up to that level without welding its contacts or cascading failure upstream — a critical spec for coordination studies in distribution boards where the prospective short-circuit current is known.
