What the ratings mean for fit
The 3VM1180-3EE46-0AA2: The 25 kA Icu at 415 V AC means this breaker can safely interrupt a fault current up to that level without welding its contacts or failing catastrophically — critical for panels fed from a transformer with high available fault current. The TM220 thermal-magnetic trip unit provides overload protection adjustable from 56 A to 80 A (Ir) and fixed short-circuit protection at 10 x In (Ii = 800 A). That 10x multiplier is typical for line protection on motor feeders or distribution sub-mains where you need to ride through starting inrush without nuisance tripping.
Panel integration notes
The 4-pole construction includes an unprotected N conductor terminal — the neutral is switched but not internally protected, so it handles the same continuous current as the phases but relies on upstream or downstream protection for fault clearance. Mounts on a standard DIN rail or panel-mount via the frame's integral lugs. Terminal connections accept copper or aluminum conductors; verify lug torque per the nameplate.
