Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 1492-JG3 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-JG3 — 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-JG3; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Q.Where can I find the rated operational voltage data for 1492-JG3?
