The Siemens 5SY4325-7CV is a 3-pole miniature circuit breaker (MCB) with a C-curve trip characteristic rated at 25 A. Its interrupting capacity is 15 kA at 400 V, which means it can safely clear a fault current up to that level without welding contacts or rupturing the case — a key spec for panel coordination studies where the available fault current at the distribution board is known to be high.
