The interrupting ratings climb with available fault current: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. No need to upsize the frame for a warm enclosure. Power loss maxes out at 22.2 W, which is modest for a 160 A frame — keeps the panel heat budget manageable.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a standard 3VA2 footprint that drops into the same mounting holes and bus-bar spacing as other 3VA2 breakers in the 160 A frame. The basic switch variant is listed as 3VA2216-5HL32-0AA0 — the -0CC0 suffix adds the factory-fitted undervoltage release and the two HQ auxiliary switches. If you're replacing a bare -0AA0, expect to land the UVR coil wires and the aux-switch terminals; the mechanical mounting is identical.
