Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The AL1402 is the device-level element in an IFM circuit breaker installation. It receives the field signals and control supply listed above — 24 V DC (IEC 61131-2) — and switches or conditions the load within the <= 440 V AC 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 distribution boards, motor protection circuits, panel feeders, 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.
IFM AL1402 — 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 AL1402; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Q.Before ordering AL1402, which storage temperature entry should be checked?
The storage temperature entry quoted above is -25...85 °C. Check the revision of the installed unit if the catalog number has been superseded.
Q.Where can I find the enclosure rating data for AL1402?
It is listed in the specification table for IFM AL1402 as IP20 (IEC 60529). Compare it with the nameplate of the installed unit before ordering.
Q.For AL1402, what does the specification table state about mounting?
The specification table lists mounting = 35 mm DIN rail (IEC 60715) for IFM AL1402. Confirm this figure against the unit currently in the panel.
Q.Can the AL1402 replace the unit currently installed in my panel?
Compare catalog number AL1402 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 AL1402 before ordering?
Match the catalog number AL1402 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
