The Siemens 3VA1332-5EF32-0AA0-ZD00 is a 3-pole IEC frame 400 circuit breaker from the 3VA1 series, rated for line protection with a TM240 thermal-magnetic trip unit.
Overload and short-circuit settings
Overload protection Ir is adjustable from 224A to 320A, and short-circuit protection Ii is set at 5 to 10 x In. 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.
