Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 17 kA at 500 V and 690 V. At 690 V the 17 kA rating still covers most industrial motor-control center lineups. Thermal derating is tight: holds 80 A all the way to 50 °C, then drops only 2 A per 5 °C step to 74 A at 70 °C. That gives you headroom in a warm enclosure without oversizing the frame. That 3-inch width matches the standard SENTRON 3VA1 three-pole envelope — fits the same DIN-rail or screw-mount backplate as the rest of the 3VA1 family. No trip indicator on the face; the UVR coil is factory-installed, so verify the control voltage matches your panel's 24 VDC or 110-240 VAC supply before wiring the release terminals. The -25 °C floor means it's fine for unheated electrical rooms in northern climates.","metaTitle":"Siemens 3VA1180-5EF32-0DA0 SENTRON MCCB, 80A, 3-Pole, 187kA","metaDescription":"Siemens 3VA1180-5EF32-0DA0 SENTRON molded case circuit breaker, 80A rated at 40°C, 3-pole, 187kA breaking capacity at 240V.
