Where it sits in the control system
The EL6751 is the device-level element in a Beckhoff 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 the rated 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.
Selection notes for Beckhoff EL6751
Beckhoff EL6751 — 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 EL6751; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Storage temperature: -40…+85°C — Match it to the existing panel and upstream protection.
- Certifications: CE, UL, cULus — Record it with the other nameplate data when sourcing a replacement.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Confirm the revision of the installed unit before a like-for-like replacement.
- Mounting: 35 mm DIN rail (IEC 60715) — Use it as the reference when cross-checking a current-production equivalent.

Common questions about EL6751
Q.For EL6751, what does the specification table state about certifications?
The specification table lists certifications = CE, UL, cULus for Beckhoff EL6751. Confirm this figure against the unit currently in the panel.
Q.Which value is published under humidity for catalog number EL6751?
For EL6751, humidity is given as 95%, no condensation. Use the value as the reference when sourcing a current-production equivalent.
Q.Before ordering EL6751, which storage temperature entry should be checked?
The storage temperature entry quoted above is -40…+85°C. Check the revision of the installed unit if the catalog number has been superseded.
Q.How do I confirm compatibility of EL6751 before ordering?
Match the catalog number EL6751 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
Q.Can the EL6751 replace the unit currently installed in my panel?
Compare catalog number EL6751 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.
