The TM120M thermal-magnetic release gives a fixed thermal pickup and a magnetic short-circuit trip that coordinates with downstream branch protection. Breaking capacity hits 220 kA at 240 V AC, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker handles high-fault utility feeds or transformer secondaries without needing a current-limiting fuse upstream. At 500 V and 690 V the rating drops to 7.5 kA, so for 480 V or 600 V class systems the fault-current capability is lower; verify your available fault current before committing the BOM line.
The 3VA1110-6MH32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard MCCB footprint that fits most 3-pole panel cutouts. Front face carries IP40 protection, so it's fine for dry indoor enclosures but not washdown areas. If your panel needs remote tripping or status feedback, you'll want a different option code in the 3VA family.
