It's designed for line protection in distribution panels where you need high fault interruption: 187 kA at 240 V, 121 kA at 415 V, and still 17 kA at 690 V. ## Interrupting ratings and thermal derating At 415 V it still clears 121 kA, which covers most industrial secondary distribution. The thermal curve is flat from 40 °C to 50 °C (full 250 A), then drops to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. If this panel lives in a hot mezzanine, size the load for the derated value at your ambient.","metaTitle":"Siemens 3VA1225-5EE32-0AA0 SENTRON MCCB, 250 A, 3-Pole, TM22","metaDescription":"Siemens SENTRON 3VA1225-5EE32-0AA0 molded case circuit breaker. 250 A continuous, 187 kA at 240 V interrupting rating. 3-pole, TM220 release.
