Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 1492-LG3T is the device-level element in an Allen-Bradley 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 DIN rail / panel support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Allen-Bradley 1492-LG3T — 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 1492-LG3T; 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 operational voltage for catalog number 1492-LG3T?
For 1492-LG3T, rated operational voltage is given as 800 V (IEC 60947-7-1). Use the value as the reference when sourcing a current-production equivalent.
Q.Before ordering 1492-LG3T, which mounting entry should be checked?
The mounting entry quoted above is DIN rail / panel. Check the revision of the installed unit if the catalog number has been superseded.
Q.Where can I find the enclosure rating data for 1492-LG3T?
It is listed in the specification table for Allen-Bradley 1492-LG3T as IP20 (IEC 60529). Compare it with the nameplate of the installed unit before ordering.
Q.Can the 1492-LG3T replace the unit currently installed in my panel?
Compare catalog number 1492-LG3T and the ratings above with the nameplate of the installed device. A current-production equivalent is selected by function and electrical rating, not by the label alone.
Q.How do I confirm compatibility of 1492-LG3T before ordering?
Match the catalog number 1492-LG3T and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
