At 415 V it still manages 75.6 kA, dropping to 52.5 kA at 440 V and 11.9 kA at 500 V or 690 V — that 11.9 kA floor is still enough for most industrial panel fault levels, but verify your available fault current at the point of installation. Thermal derating is minimal up to 50 °C (still 80 A), then slides to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That means a panel at 50 °C ambient gets full rating; above that you lose about 1 A per 5 °C. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard Siemens SENTRON mounting plates and panel cutouts. The undervoltage release (UVR) is factory-fitted, so no field wiring of a separate shunt trip module.","metaTitle":"Siemens SENTRON 3VA1180-4EF32-0BC0 MCCB, 80A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1180-4EF32-0BC0 molded case circuit breaker, 80A rated, 3-pole, 121kA interrupting at 240V.
