The TM240 thermal-magnetic trip unit gives you adjustable overload protection from 224 A to 320 A, and short-circuit pickup set at 5 to 10 times the rated current In=320 A. In a real panel, you'd coordinate this with upstream and downstream devices to keep the arc energy contained within the breaker's rating — standard selectivity practice per IEC 60947-2. The TM240 thermal unit is adjustable via a rotary dial on the front face, letting you set the Ir between 224 A and 320 A to match the continuous load without swapping the trip unit. The magnetic short-circuit pickup Ii is fixed at 5-10x In (1600-3200 A), which is typical for motor and feeder protection — fast enough to clear a bolted fault, but rides through motor inrush.","metaTitle":"Siemens 3VA1332-5EF32-0CG0 Circuit Breaker, 55kA @ 415V, 320","metaDescription":"Siemens 3VA1332-5EF32-0CG0 IEC frame 400 MCCB, 55kA breaking capacity @ 415V, 3-pole, TM240 thermal-magnetic trip, 320A.
