What matters for the BOM line is the breaking capacity: 187 kA at 240 V AC, 121 kA at 415/440 V, 79 kA at 500 V, and 4.25 kA at 690 V.
If you're swapping out an older 3VA1 or a competitor's 3-pole MCCB, check the mounting hole pattern; the 3VA2 series uses the same bolt spacing as the previous generation, so a drop-in replacement is likely without redrilling the backplate.
Environmental and endurance data
For a main feeder breaker that cycles a few times a year, that's effectively a lifetime. Maximum power loss is 4 W, which is negligible for panel thermal calculations.
This is a current-production part with no obsolescence signals. The manufacturer lists it as 'current' lifecycle stage. No minimum order quantity is implied by the lifecycle status. The official base variant is 3VA2163-5HL32-0AA0 (without the auxiliary switch option); the -0AG0 suffix adds the 1 auxiliary + 1 alarm switch configuration.
