That puts it in the high-interrupting tier for 400 V distribution; you are looking at a breaker sized for main or heavy feeder duty in an industrial panel, not a branch device.
The suffix ZD00 indicates a China DC Power OEM configuration with a nut keeper kit. That means the breaker ships with hardware intended for a specific OEM panel build, not a generic off-the-shelf unit. If you are backfilling a BOM line for that OEM install, this is the exact match. For general distribution use, verify the accessory kit matches your mounting scheme.
Four-pole construction means it occupies four module widths — plan for roughly 280 mm of rail space plus clearance for cable entry and arc-chute exhaust. The nut keeper kit simplifies captive-fastener installation in OEM jigs.
