The interrupting capacity is what you notice: 330 kA at 240 V, and still 242 kA at 415 V and 440 V. That's serious fault-clearing muscle for a motor control center fed off a high-capacity transformer. At 55 °C it's 495 A, at 60 °C it's 490 A, at 65 °C it's 485 A, and at 70 °C it's 480 A. If your enclosure ambient runs hot, that's a clean derate curve to work with. That's a hard requirement for motor protection — a single-phased motor draws locked-rotor current on the remaining phases and cooks the winding if the breaker doesn't trip. This one does. Footprint is 138 mm wide, 248 mm tall, 110 mm deep. That's a standard 3-pole MCCB envelope for this current class — it'll fit Sentron panel cutouts and most MCC bucket layouts without re-drilling. This is an active, in-production Siemens SENTRON catalog line. For a BOM-critical MCCB like this, you want to source it through a distributor who can quote firm pricing and lead time against an RFQ — not gamble on spot-market availability. We can do that: send the order code and quantity, and we'll come back with a quote and a delivery window.","metaTitle":"Siemens 3VA2450-7MN32-0AA0 SENTRON MCCB, 500A, 3-Pole Motor","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0AA0 molded case circuit breaker, 500 A continuous, 3-pole motor protection.
