Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The AL1303 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 AL1303 — 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 AL1303; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
