The 80 A holds flat from 40 °C through 50 °C, then derates to 72 A at 70 °C — that thermal curve matters if this breaker lives in a hot panel or near other heat sources. Short-circuit breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The auxiliary contact configuration is factory-integrated — no field add-on required. The integrated auxiliary trip order code is 3VA9608-0BB25.
Mechanical endurance is rated at 15,000 operations. The TM240 release is a fixed thermal-magnetic design — no interchangeable trip units. For DC network applications, refer to the 3VA device manual for switching power values.
