Where it sits in the control system
The EL1859 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 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 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 EL1859
Beckhoff EL1859 — 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 EL1859; record the nameplate data of the unit being replaced before selecting an equivalent.
- Communication ports: EtherCAT, Ethernet — Use it as the reference when cross-checking a current-production equivalent.
- Tripping characteristic: 8…9 mm — Verify it in the project documentation before confirming the order.
- Rated operational voltage: 24 V DC (-15%/+20%) — Check this value against the nameplate of the installed unit before ordering.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Match it to the existing panel and upstream protection.

Common questions about EL1859
Q.Which value is published under mounting for catalog number EL1859?
For EL1859, mounting is given as 35 mm DIN rail (IEC 60715). Confirm this figure against the unit currently in the panel.
Q.Before ordering EL1859, which bus interface entry should be checked?
The bus interface entry quoted above is typ. 130 mA. Use the value as the reference when sourcing a current-production equivalent.
Q.Where can I find the weight data for EL1859?
It is listed in the specification table for Beckhoff EL1859 as approx. 65 g. Check the revision of the installed unit if the catalog number has been superseded.
Q.Can the EL1859 replace the unit currently installed in my panel?
Compare catalog number EL1859 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.What should I include in an enquiry for EL1859?
Send the full catalog number EL1859, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for Beckhoff EL1859.
