It's configured for line protection with a TM240 thermal-magnetic trip unit, ATAM, and an In=500A rating. This variant includes a nut keeper kit and is specified for a DC Power OEM in China. For a 500A frame, that's a high-capacity class H rating, suited for industrial distribution panels with high available fault current. The adjustable Ir (350A to 500A) lets you dial in the overload protection to match the downstream load without swapping trip units. The Ii range of 5 to 10 x In means the magnetic short-circuit pickup is set between 2500A and 5000A, which avoids nuisance tripping on motor inrush while still clearing hard faults. ## Panel Integration The nut keeper kit included with this variant is a small but practical detail: it prevents the mounting nuts from dropping into the enclosure during installation, saving a few minutes on the line. For a DC Power OEM build in China, that kit is already spec'd in.","metaTitle":"Siemens 3VA1450-6EF32-0AA0-ZD00 Circuit Breaker, 500A, 70kA","metaDescription":"Siemens 3VA1450-6EF32-0AA0-ZD00 IEC frame 630 circuit breaker, 3-pole, 500A, 70kA breaking capacity @ 415V.
