Line protection MCCB with shunt trip and auxiliary switches
Its breaking capacity reaches 187 kA at 240 V and 121 kA at 415 V, with a derated 4.5 kA at 690 V. Maximum power loss is 48 W.
At 500 V the rating drops to 75.6 kA, and at 690 V to 4.5 kA — the latter limits its use on 690 V networks to locations with low available fault current. Compared to a smaller-frame sibling like the 3VA2116-5HL32-0AK0, the 3VA2225-5HN42-0HL0 carries a higher continuous rating and a different auxiliary switch complement. Panel cutouts and mounting pattern differ; verify footprint before assuming drop-in replacement. The base switch is 3VA2225-5HN42-0AA0; the -0HL0 suffix adds the shunt trip and auxiliary switch package. If your BOM specifies the -0AA0, this variant provides additional control wiring that must be accounted for.
Environmental and compliance range
The thermal derating curve above 50 °C must be applied for continuous load calculations.
