The 3VA2463-5HN32-0AB0 delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — the 415 V figure is the one most panel builders will size against for 400 V class distribution. Maximum power loss is 162 W, which drives ventilation requirements in sealed cabinets.
The breaker ships with 2 auxiliary switches (HP type) pre-installed; no undervoltage release, ground-fault monitoring, or communication function is included.
121 kA at 415 V AC, which is the typical rating used for 400 V class industrial distribution panels.
The 3VA2463-5HN32-0AB0 is a SENTRON 3-pole MCCB with standard mounting dimensions (248 x 138 x 110 mm). It will physically fit most SENTRON-compatible bases, but verify the base model and busbar arrangement against your existing panel layout — the auxiliary switch wiring differs from the 5SQ2370 series.
