Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and still holds 11.9 kA at 690 V.
Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a standard 4-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboards without re-drilling.
What the TM220 release means for coordination
The TM220 designation means a fixed thermal pickup and a magnetic trip that is adjustable across a 5–10x In range. For a 100 A breaker, that puts the instantaneous magnetic trip between 500 A and 1000 A. That adjustability lets you coordinate downstream with branch-circuit breakers or motor starters without oversizing the feeder.
