The TM240 trip is rated In=320A, with Ir adjustable 224A...320A and Ii adjustable 5...10 x In. The 3VA1 frame is a standard panel-mount design — it bolts into a switchboard or enclosure bus, not a DIN rail. The nut keeper kit (included) holds the mounting nuts captive, speeding installation in tight panel layouts.","metaTitle":"Siemens 3VA1332-5EF32-0AC0 Circuit Breaker, 55kA @ 415V, 320","metaDescription":"Siemens 3VA1332-5EF32-0AC0 IEC frame 400 MCCB, 55kA @ 415V breaking capacity, 320A TM240 thermal-magnetic trip, adjustable Ir 224-320A, Ii 5-10xIn.
