Rated and Locked: 3VA1180-6GE42-0AA0-ZD00
The Siemens 3VA1180-6GE42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with a breaking capacity class H rating of Icu=70kA at 415 V. The TM220 thermal-magnetic trip unit gives you overload protection adjustable from Ir=56 A to 80 A, and a fixed short-circuit pickup of Ii=10 x In. If you're specifying this into a panel, the 100% N-conductor protection and the nut keeper kit for DC Power OEM in China are part of the build; verify the keeper kit matches your bus-bar stack-up before the BOM locks.
The TM220 thermal-magnetic trip provides inverse-time overload protection (the thermal element) and instantaneous magnetic trip at 10 x In (800 A for the 80 A rating). That 10 x In pickup is typical for motor branch circuits where you need to ride through inrush without nuisance tripping. The adjustable Ir (56 A to 80 A) lets you fine-tune the continuous current rating to the actual load, which is useful when the connected load is less than the breaker's In.
