Breaking capacity is voltage-dependent: 52.5 kA at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V, so the interrupting rating you need drives the voltage tap you spec it on.
Auxiliary and release configuration
That means it can signal its status to a PLC or annunciator without an add-on module — useful for remote trip indication. The basic switch variant is 3VA10102ED320AA0, so if you need the same mechanical footprint with a different release, that order code is the starting point for the base breaker.
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboards. The 3-pole design covers three-phase line protection. Power loss is 25 W maximum, so factor that into your enclosure thermal budget if you are packing multiple breakers side by side.
