Power loss maxes at 37.5 W — useful to know for enclosure thermal budgeting. At 415 V and 440 V the breaker still clears 121 kA; at 500 V it's 75.6 kA; at 690 V it drops to 7.5 kA. That steep derating above 500 V means this frame is really optimized for 240–480 V systems — common in North American and European industrial distribution. ## Thermal performance and ambient derating The 250 A rating holds flat from 40 °C through 70 °C — no derating needed across the typical panel ambient range. Operating range is -25 °C to 70 °C; storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA2325-5JQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2325-5JQ42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, 187 kA at 240 V.
