Overload protection is adjustable via a TM220 thermal-magnetic trip unit: Ir from 88 A to 125 A, so you dial in the continuous current to match the cable or load. Short-circuit protection is fixed at Ii = 10 x In (1250 A), which is typical for line protection where you want fast magnetic trip on hard faults but avoid nuisance tripping on motor inrush.
Same part, different passport — this unit includes a nut keeper kit configured for a DC Power OEM in China. That means the breaker itself is a standard 3VA1 IEC frame 160 device, but the accessory kit and packaging are tailored for that OEM channel.
Integration notes for the panel builder
The 3-pole footprint fits a 160 A frame cutout; plan for 3 x 70 mm² cable terminations on the line and load side. The TM220 trip unit is field-adjustable without removing the cover — just rotate the dials for Ir and Ii.
