The Siemens SENTRON 3VA2225-6JP32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 250 A continuous at 40 °C through 50 °C without derating. At 240 V it interrupts 242 kA — that's the short-circuit rating that governs fault clearance upstream of a transformer or a high-fault panel. At 415 V and 440 V it holds 187 kA, dropping to 121 kA at 500 V and 4.5 kA at 690 V. Thermal derating starts at 55 °C — 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C.
The 105 mm width per pole (35 mm per pole) is standard for SENTRON 3VA breakers; a 3-pole unit occupies three 35 mm DIN slots if base-mounted, or bolts directly to a mounting plate.
