What sets this MCCB apart is the interrupting capacity: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. ## Thermal derating and ambient limits At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, and at 70 °C to 72 A. The 3VA1180-6EF36-0BA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The mechanical endurance is rated at 15 000 operations — that's typical for a distribution MCCB; it's not a switching device for frequent motor starts.","metaTitle":"Siemens 3VA1180-6EF36-0BA0 SENTRON MCCB, 80 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1180-6EF36-0BA0 molded case circuit breaker, 3-pole, 80 A rated continuous current, 220 kA breaking capacity at 240 V.
