It carries a TM210 thermal-magnetic release — the fixed thermal element and fixed magnetic trip are factory-set, so no field adjustment of the trip curve is needed. This is the version you spec when the BOM calls for a non-communicating, no-ground-fault, no-N-conductor-protection MCCB that simply clears overloads and short circuits in a distribution panel. This MCCB delivers 52.5 kA at 240 V AC, 32 kA at 415 V AC, 13.6 kA at 440 V AC, and 7.5 kA at both 500 V and 690 V AC. ## Thermal derating — don't size on the 40 °C number alone Above that, it starts to taper: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The thermal element in the TM210 release responds to ambient heat, so a hot panel reduces headroom. The breaker occupies 101.6 mm (4 in) of width on the DIN rail or mounting plate, with a depth of 70 mm (2.76 in) and height of 130 mm (5.12 in). That width is the critical dimension for multi-breaker layouts — a 4-pole at 101.6 mm means it takes the same space as two standard 2-pole 3VA frames side by side. Max power dissipation is 19.2 W — negligible for thermal planning in a ventilated panel, but worth noting if the breaker is in a sealed, densely packed cabinet. Maximum rated operational voltage with DC is 600 V.","metaTitle":"Siemens 3VA1080-2ED42-0AA0 SENTRON MCCB, 80A, 4-Pole, TM210","metaDescription":"Siemens 3VA1080-2ED42-0AA0 SENTRON molded case circuit breaker, 80 A continuous, 4-pole, TM210 thermal-magnetic release. 52.5 kA at 240 V, 32 kA at 415 V.
