It sits in the 3VA2 frame, which is the high-breaking-capacity branch of the SENTRON family — the interrupting ratings tell the story: 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. Thermal derating is published across the full temperature band: 630 A at 40 °C, stepping down to 450 A at 70 °C.
Built-in communication and auxiliary switching
This variant includes a communication function — the 3VA2 frame accepts the SENTRON communication module for remote monitoring and trip indication over PROFIBUS or PROFINET, depending on the module fitted. The shunt trip release (STL) is factory-fitted, so remote tripping via a control signal is ready out of the box — no field retrofit of the release coil.
Dimensions are 248 mm height, 138 mm width, 110 mm depth — that is 9.76 by 5.43 by 4.33 inches. The 3-pole footprint is standard for this frame size; verify the busbar or cable lug centres match your existing panel layout.
