It's rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C, so no derating headache when the panel runs hot. The 3-pole construction handles three-phase systems, and the breaking capacity at 240 V hits 330 kA — that's high enough for most industrial service-entrance or sub-distribution applications where fault current is substantial.
Breaking capacity across voltage levels
This MCCB's interrupting rating varies with system voltage: 330 kA at 240 V, 242 kA at both 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V tells you this is a 500 V-class frame — if your system runs 690 V, the 3.7 kA limit may be tight for high-fault installations. For standard 480 V or 600 V class panels, the 187 kA at 500 V gives comfortable margin.
The 3VA2163-7HN32-0AC0 measures 105 mm wide, 181 mm tall, and 86 mm deep. The 86 mm depth means it clears shallow enclosures where deeper frames would hit the backplate or door.
