SENTRON 3VM1180-4EE32-0AA0 — 80 A MCCB with TM220 Release
It carries a TM220 thermal-magnetic release — the thermal element handles overloads, the magnetic element clears short-circuits — and delivers a breaking capacity of 121 kA at 240 V AC, stepping down to 76 kA at 415 V, 53 kA at 440 V, and 12 kA at 500 V.
Above that, derating is gradual: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The TM220 release's thermal element responds to I²t heating, so ambient temperature directly shifts the trip curve; the derating table is the manufacturer's pre-validated compensation.
The 3-pole footprint matches the standard SENTRON 3VM family cutout; if you are swapping a failed breaker in an existing panel, measure the mounting base — the 70 mm depth leaves clearance for rear-connected busbars or cable lugs.
