It carries the ETU350M electronic trip unit, configured for motor protection — meaning it tracks phase failure and thermal overload, not just short-circuit clearing. At 55 °C it drops to 495 A, at 60 °C to 490 A, at 65 °C to 485 A, and at 70 °C to 480 A. The ETU350M release is an electronic trip unit — no thermal bimetal, so ambient temperature compensation is built in. Phase failure detection is standard, which is the main reason you'd pick this over a basic thermal-magnetic MCCB for motor branch circuits. That depth is the body only — allow extra for the auxiliary switch wiring (2 HP auxiliary switches are fitted) and for the arc-chamber clearance per IEC 60947-2.","metaTitle":"Siemens 3VA2450-7MN32-0AB0 MCCB, 500 A, 330 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0AB0 molded case circuit breaker, 500 A rated continuous current, 330 kA at 240 V, motor protection, ETU350M release, IP40 front.
