The key spec for a sourcing decision is the breaking capacity: 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — that's the fault current it can safely interrupt without welding contacts or venting plasma.
That means it's ready for remote tripping and status feedback out of the box — no extra wiring of add-on modules on the bench. The 76.2 mm width and 70 mm depth fit the standard SENTRON 3VA panel footprint; if you're swapping into an existing 3VA cutout, the bus-bar centers and DIN-rail clip pattern are identical across the family. Power loss is 8.5 W maximum, so thermal rise inside a sealed enclosure is manageable with standard venting.
