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.","metaTitle":"Siemens 3VM1180-4EE32-0AA0 SENTRON MCCB, 80A, 3-Pole, TM220","metaDescription":"Siemens SENTRON 3VM1180-4EE32-0AA0 molded case circuit breaker, 80A rated at 40°C, 3-pole, TM220 release.
