Its 80 A rating at 40 °C (derated to 74 A at 70 °C) covers feeder and branch circuits in commercial and industrial switchboards.
Interrupting capacity across voltages
The interrupting rating drops as system voltage rises: 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V.
Shunt trip release and auxiliary options
This variant carries a shunt trip (STL) release for remote tripping via a control voltage. The supplied basic switch is order code 3VA11806EF320AA0.
Panel integration: dimensions and mounting
The 76.2 mm width (3 in) is the standard SENTRON 3VA frame footprint — fits existing panel cutouts and busbar arrangements for the 3VA family.
