The 2904477 is the device-level element in a Phoenix Contact terminal block installation. It receives the field signals and control supply listed above — 800 V (IEC 60947-7-1) — and switches or conditions the load within the up to 41 A (IEC 60947-7-1) 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 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
