Breaking capacity runs from 440 kA at 240 V down to 52.5 kA at 690 V, so it handles high-fault utility feeds without cascading upstream. Insulation voltage is rated at 800 V (Ui). Front protection is IP40; the breaker is designed for panel-mount integration with a depth of 86 mm, width of 140 mm, and height of 181 mm.
The 4-pole footprint matches standard SENTRON 3VA2 drilled patterns, so a panel already punched for a 3VA2 frame should accept this drop-in. An optional motor drive (product extension) is available for remote switching. The ETU550 trip unit communicates over the integrated communication function; plan for a wiring channel to the controller or BMS.
