Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 2744458 is the device-level element in a Phoenix Contact terminal block installation. It receives the field signals and control supply listed above — 19.2 V AC/DC ... 28.8 V AC/DC — 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.
Phoenix Contact 2744458 — Industrial automation component supplied as a like-for-like replacement, selected by catalog number and published ratings. The figures below are taken from the specification table on this page for catalog number 2744458; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Q.Which value is published under rated current Ie for catalog number 2744458?
For 2744458, rated current Ie is given as up to 41 A (IEC 60947-7-1). Compare it with the nameplate of the installed unit before ordering.
