The 250 A rating holds flat from 40 °C to 50 °C, then derates linearly to 213 A at 70 °C. If the breaker lives in a hot enclosure or next to other heat sources, use the 60 °C column (232 A) or 70 °C column (213 A) for your load calculation — not the nameplate 250 A. The rated insulation voltage is 800 V, and the maximum operating voltage is 690 V AC, so it is suitable for 400/480 V and 600/690 V class systems. Maximum power dissipation is 48 W at rated load — plan for that heat in your enclosure thermal budget.","metaTitle":"Siemens 3VA2225-8HN32-0AA0 SENTRON MCCB, 250 A, 3-Pole, 440","metaDescription":"Siemens SENTRON 3VA2225-8HN32-0AA0 molded case circuit breaker. 250 A continuous, 3-pole, 440 kA breaking at 240 V AC.
