That interrupting capacity means it can clear high-fault events without upstream devices needing to trip, which simplifies coordination in a multi-level distribution system. This is common in safety circuits where a loss of control power must disconnect the load. It also ships with 2 auxiliary switches HQ (high-qualified) for remote status indication, so a PLC or SCADA can see open/closed state without an additional contact block. Above that, the thermal element derates: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The auxiliary trip unit (order code 3VA9608-0BB25) is a separate accessory that plugs into the breaker's accessory slot.","metaTitle":"Siemens 3VA1080-3ED42-0DC0 SENTRON MCCB, 80 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1080-3ED42-0DC0 molded case circuit breaker, 80 A rated, 4-pole, 75.6 kA at 240 V.
