At 415 VAC it's 242 kA, and at 690 VAC it drops to 4.5 kA. That steep derating is normal for an air-break MCCB; the arc extinguishes faster at lower voltages. For a site engineer coordinating with upstream breakers, the 242 kA at 415 V still gives plenty of headroom for most industrial secondary distribution. The 250 A continuous rating holds steady from 40 °C up to 50 °C, then derates to 200 A at 70 °C — useful to know if the panel sits near a heat source. ## Built-in communication and auxiliary contacts This MCCB includes a communication function — it can report status and trip events over a fieldbus or Ethernet connection, depending on the communication module fitted. It also ships with two auxiliary switches (HQ type) for local indication or PLC input. The basic switch base is 3VA2225-7KP32-0AA0, meaning the trip unit and frame are matched from the factory.","metaTitle":"Siemens SENTRON 3VA2225-7KP32-0AC0 MCCB, 250 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0AC0 molded case circuit breaker, 3-pole, 250 A rated, 330 kA breaking at 240 VAC.
