The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and still 75.6 kA at 500 V, so it handles high-fault utility feeds and large motor branch circuits without cascading upstream.
The 3VA2163-5MN32-0KL0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. Power loss is 4 W maximum, so heat dissipation is minimal inside a sealed cabinet. The shunt trip release allows remote tripping from a PLC or emergency-stop circuit, and the auxiliary switch complement gives you two form-C contacts for status feedback plus separate trip and alarm signals.
