Built-in phase failure detection and communication capability make it suitable for motor control centers where you need remote status or trip indication — it's not a dumb thermal-magnetic; it talks back. ## Panel fit and thermal reality Footprint is 138 mm wide by 248 mm tall by 110 mm deep — standard SENTRON 3VA form factor for this frame size. Rated 500 A continuous up to 50 °C ambient. Above that, derate linearly: 477 A at 55 °C, 455 A at 60 °C, 432 A at 65 °C, 410 A at 70 °C. In a sealed, uncooled enclosure near other heat sources, expect to apply that derating.","metaTitle":"Siemens 3VA2450-7MP32-0AA0 SENTRON MCCB, 500 A, 3-Pole Motor","metaDescription":"Siemens SENTRON 3VA2450-7MP32-0AA0 molded case circuit breaker, 500 A continuous, 3-pole motor protection. 330 kA at 240 V interrupting capacity.
