That means in a warm panel (say, 55 °C inside the enclosure) you lose only 2 A of headroom; the TM210 release still provides reliable overload protection. The 70 mm depth and 50.8 mm width (2.8 in × 2 in) fit the standard SENTRON 3VA mounting footprint, so it drops into existing 3VA panel layouts without re-drilling. Rated insulation voltage Ui is 500 V, and max rated operational voltage with DC is 250 V — so it's suitable for 480 V AC distribution and 250 V DC circuits. The adjustable short-circuit release Ii is fixed at 800 A (both min and max), meaning the magnetic trip threshold is non-adjustable on this TM210 variant. Latching endurance is 20 000 operations — adequate for a distribution breaker that sees infrequent switching.","metaTitle":"Siemens 3VA1180-5ED26-0AA0 SENTRON MCCB, 80 A, 2-Pole, 187 k","metaDescription":"Siemens 3VA1180-5ED26-0AA0 SENTRON 2-pole MCCB, 80 A rated, 187 kA at 240 V, TM210 release.
