The 110 mm depth and 184 mm width fit standard SENTRON mounting patterns; the integrated communication function allows remote trip indication and load monitoring without an add-on module.
At 55 °C it drops to 375 A, at 60 °C to 350 A, and at 70 °C to 300 A. That thermal curve is the real selection gate: a panel that runs at 55 °C ambient loses 25 A of headroom. The 4 000 A maximum short-time rating and 600 A minimum let you coordinate selectively with downstream breakers, keeping a faulted branch from taking the whole board dark. Interrupting capacity drops sharply above 500 V: 75.6 kA at 500 V, then 7.5 kA at 690 V. Power loss is 96 W maximum at rated load.
Integration and accessories
The 110 mm depth and 248 mm height fit the SENTRON mounting footprint — no panel rework if you're replacing a 3VA2 frame. The undervoltage release is not fitted, so if UVR is required for your safety circuit, order that variant or add the release separately.
