The design is line protection, so it is the primary overcurrent device feeding a distribution bus or a large motor control center. ## Breaking capacity and derating Breaking capacity drops with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The 80 A rating holds steady from 40 °C through 50 °C; above that it derates to 78 A at 55 °C and 74 A at 70 °C — relevant if the breaker sits in a hot enclosure or near other heat sources. The 3-pole body fits standard DIN-rail or panel-mount MCCB footprints — verify the bus-bar spacing and lug centerline against your existing panel layout. The supplied basic switch is order code 3VA11805EE320AA0, which is the internal switching mechanism; the -0BC0 suffix adds the undervoltage release and auxiliary switches as a factory-assembled variant.","metaTitle":"SENTRON 3VA1180-5EE32-0BC0 MCCB, 80A, 3-Pole, 187kA at 240V","metaDescription":"SENTRON 3VA1180-5EE32-0BC0 molded case circuit breaker, 80A rated, 3-pole, 187kA breaking capacity at 240V AC.
