The TM210 thermal-magnetic overcurrent release is fixed, not adjustable. Breaking capacity is the headline spec here: 121 kA at 240 V AC, 76 kA at 415 V, 53 kA at 440 V, and 12 kA at 500 V. That covers most industrial distribution panels fed from a transformer secondary. For DC applications, the manual provides specific values up to 500 V.
That is a standard 4-pole MCCB width for a 125 A frame.
Maximum power loss is 23 W.
The 3VM1112-4ED42-0AA0 is from the SENTRON 3VM series, not the 3VA series. Physical dimensions (101.6 mm width) and mounting may differ; verify panel cutout and busbar spacing before substituting.
