80 A MCCB with high interrupting capacity for line protection
It carries a TM210 thermal-magnetic overcurrent release — the fixed thermal element handles overloads, the magnetic trip handles short-circuits up to 75.6 kA at 240 V and 52.5 kA at 415 V. 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.
