Rated current holds flat at 500 A up to 50 °C ambient, then derates to 495 A at 55 °C and 480 A at 70 °C — useful if the breaker sits in a warm enclosure near other heat sources. Maximum power loss is 99 W — relevant for enclosure thermal calculations and ventilation sizing. The short-time withstand rating is 6 kA limited to 1 second — coordination engineers need this for downstream selectivity with smaller breakers.","metaTitle":"Siemens 3VA2450-7MN32-0HC0 SENTRON MCCB, 500 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0HC0 molded case circuit breaker, 3-pole, 500 A rated, 330 kA breaking capacity at 240 V.
