Where it sits in the control system
The EL5101 is the device-level element in a Beckhoff circuit breaker installation. It receives the field signals and control supply listed above — 10...30 V DC — and switches or conditions the load within the 24 V DC (-15%/+20%) 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 double slot and key connection 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 EL5101
Beckhoff EL5101 — 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 EL5101; verify the catalog number against your bill of materials before requesting a quotation.
- Humidity: 95%, no condensation — Verify it in the project documentation before confirming the order.
- Enclosure rating: IP65 / IP67 (IEC 60529) — Check this value against the nameplate of the installed unit before ordering.
- Communication ports: EtherCAT, Ethernet — Match it to the existing panel and upstream protection.
- Encoder type: 5 V DC/max. 0.5 A (generated from the 24 V DC power contacts) — Record it with the other nameplate data when sourcing a replacement.
Cross-check the ratings above with the installed device before confirming the order.
Common questions about EL5101
Q.Before ordering EL5101, which tripping characteristic entry should be checked?
The tripping characteristic entry quoted above is 8…9 mm. Check the revision of the installed unit if the catalog number has been superseded.
Q.Where can I find the bus interface data for EL5101?
It is listed in the specification table for Beckhoff EL5101 as typ. 130 mA. Compare it with the nameplate of the installed unit before ordering.
Q.For EL5101, what does the specification table state about dimensions (H x W x D)?
The specification table lists dimensions (H x W x D) = 24 mm x 100 mm x 68 mm for Beckhoff EL5101. Confirm this figure against the unit currently in the panel.
Q.What should I include in an enquiry for EL5101?
Send the full catalog number EL5101, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for Beckhoff EL5101.
Q.Can the EL5101 replace the unit currently installed in my panel?
Compare catalog number EL5101 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.
