The Siemens 3VA1332-4EE32-0AA0-ZD00 is a 3VA1 IEC frame 400 molded case circuit breaker, 3-pole, rated In=320A with a breaking capacity class S giving Icu=36kA at 415V AC. Overload protection is set via the TM220 thermal-magnetic trip unit with an adjustable Ir range of 224A to 320A, and short-circuit pickup Ii fixed at 10 x In (3200A). The ATFM designation indicates it's a fixed thermal, fixed magnetic, line-protection trip — no electronic adjustments, no ground-fault module.
