Breaking capacity is voltage-dependent: 187 kA at 240 V, dropping to 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. No communication function on this variant; it's a straight electromechanical protector.
Panel fit and physical integration
The 105 mm width for a 3-pole 200 A unit is standard for the SENTRON 3VA platform; it'll drop into the same DIN-rail or screw-mount footprint as other 3VA frame-size breakers. That's not trivial in a sealed enclosure — account for the heat when sizing ventilation or calculating internal temperature rise.
