Breaking capacity is the real selector for this class. At 240 V it clears 187 kA — that's transformer-secondary territory. At 415 V it's 121 kA, at 440 V it's 75.6 kA, and at 690 V it's 17 kA. That matters for selective coordination studies. Physical footprint: 105 mm wide, 158 mm tall, 70 mm deep. The undervoltage release coil draws its supply from the line side — no separate control transformer needed for the trip function, but verify the dropout threshold matches your system's brownout settings. Auxiliary contacts (2 NO/NC + 1 trip alarm) are pre-wired to a terminal block on the breaker face. The trip alarm switch changes state on a fault trip regardless of handle position — useful for remote fault indication without a shunt trip.","metaTitle":"Siemens SENTRON 3VA1220-5EF32-0BH0 MCCB, 200 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0BH0 molded case circuit breaker, 200 A at 40 °C, 3-pole, 187 kA at 240 V.
