The SENTRON 3VA1180-5EE32-0BC0 is a 3-pole molded case circuit breaker (MCCB) rated 80 A continuous at 40 °C, with a breaking capacity of 187 kA at 240 V AC — that is the headline number for fault-interruption duty, and it means this breaker can safely clear a bolted fault up to that level without welding its contacts or cascading the arc upstream. 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.
