Product details

Its continuous current rating is 630 A at 40 °C, with a full thermal derating curve down to 450 A at 70 °C — so the actual ampacity in a warm panel is the number to spec, not the 40 °C headline. At the common 415 V industrial bus, it interrupts 187 kA — that's the figure a fault-current study checks against. The electronic trip unit is adjustable between 945 A and 5 670 A (minimum to maximum), with a full-scale value of 630 A. No trip indicator, but undervoltage release is built in as a shunt trip (STL).

Maximum power loss is 162 W at rated load. That heat stays inside the enclosure; factor it into the panel's thermal budget alongside drives and contactors.

The base switch variant is 3VA2463-6JQ32-0AA0; this -0KC0 suffix adds the shunt trip and auxiliary switch complement. If a BOM line already carries the -0AA0, verify the auxiliary configuration matches before substituting.
