The TM120M thermal-magnetic release gives a fixed thermal trip at 80 A and a magnetic short-circuit pickup tuned for motor inrush, so it holds through starting current but clears a bolted fault fast.
This MCCB carries a 187 kA interrupting rating at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V. Those are high numbers — it's a current-limiting breaker designed to handle severe fault conditions on the line side of a motor starter. At 500 V and 690 V the rating drops to 7.5 kA, so it's still usable on 480/600 V systems but only where the available fault current stays under that threshold.
Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
The 3VA1180-5MH32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint that fits standard SENTRON panel layouts.
