Breaking capacity is the other number that decides fit. At 240 V it clears 187 kA; at 415 V it's still 121 kA. Drop to 500 V and it handles 75.6 kA. At 690 V it's 7.5 kA — still enough for most industrial service-entrance applications but that's the limit. If your fault-current study comes in above the 690 V figure, this isn't the frame.
What's built in — auxiliary switch and undervoltage release
Factory-fitted with 2 HQ auxiliary switches and an undervoltage release (UVR). The basic switch platform is 3VA2325-5HN32-0AA0, meaning the aux and UVR are pre-assembled at the factory, not field-add-on kits.
Footprint is 110 mm deep, 138 mm wide, 248 mm tall. Bolts into a standard MCCB mounting plate or DIN-rail adapter. No communication module onboard — this is a straight line-protection device, no Modbus or PROFIBUS bridge inside.
