Derating and thermal reality for panel builders
At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, at 65 °C to 73.6 A, and at 70 °C to 72 A. The breaker measures 76.2 mm wide, 130 mm high, and 70 mm deep, so it fits standard SENTRON 3VA panel footprints.
Auxiliary and shunt trip configuration
The shunt trip allows remote tripping via a separate control voltage — useful for emergency-stop circuits or supervisory shutdown. There is no undervoltage release, no ground fault monitoring, no phase failure detection, and no communication function. The integrated auxiliary trip order code is 3VA9688-0BL30, which is the factory-installed accessory. If you need undervoltage release or ground fault, you are looking at a different 3VA variant.
