All variants share the same Residual Current Device footprint and terminal layout; the columns above show where they differ. Selecting a different catalog number changes the electrical interface, not the mounting.
The DDA804AC-63/0.03 is the device-level element in an ABB industrial component installation. It receives the field signals and control supply listed above — 230 / 400 V AC — and switches or conditions the load within the 63 A ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides DIN rail / panel support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Q.What supply does this device require?
It requires 230 / 400 V AC. Size the supply source to the same rating shown in the Specifications table.
Q.What are the key electrical ratings?
The confirmed ratings include 63 A and CE, UL, CSA, CCC marking. Cross-check them against the installed unit's nameplate.
Q.How is this device mounted?
It mounts by DIN rail / panel. Confirm the cutout or rail before ordering a like-for-like spare.
Q.What is the operating temperature range?
The confirmed operating range is 0...+55 °C (IEC 60068-2-1). Panels running beyond it need derated sizing.
Q.What replaces a unit that is no longer in production?
For a like-for-like spare, record the catalog number and revision from the nameplate; a current-production equivalent is identified by matching function and ratings.
