That adjustability lets you dial in the trip curve to match the downstream load without swapping the breaker — useful when the BOM calls for a 320A frame but the actual motor or transformer FLA sits lower.","metaTitle":"Siemens 3VA1332-5EF32-0AA0-ZD00 Circuit Breaker, 320A, 55kA","metaDescription":"Siemens 3VA1332-5EF32-0AA0-ZD00 IEC frame 400, 3-pole, 320A, Icu=55kA @ 415V.
