At 415 V and 440 V it still holds 121 kA, dropping to 75.6 kA at 500 V and 3 kA at 690 V, which covers most industrial low-voltage systems.
That's a solid spec for a warm MCC bucket or a crowded switchboard. The 3-pole configuration handles three-phase loads; the line protection design means it's set up for cable and busbar protection, not motor overload — pair it with a separate overload relay if feeding a motor directly. Communication function is onboard, so it can talk to a BMS or SCADA system for trip status and load monitoring without an add-on module.
Where it fits and how it mounts
What the spec table doesn't tell you
The trip indicator is present — a mechanical flag or window that shows the breaker has tripped, even if the handle is reset. The supplied basic switch is order code 3VA20105KP320AA0 — that's the internal switching mechanism; not something you'd replace in the field, but it confirms the breaker is a complete, factory-assembled unit, not a kit.
