Where it sits in the control system
The 2891390 is the device-level element in a Phoenix Contact 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 Phoenix Contact 2891390
Phoenix Contact 2891390 — 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 2891390; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Certifications: CE, UL, cULus — Check this value against the nameplate of the installed unit before ordering.
- Mounting: 35 mm DIN rail (IEC 60715) — Match it to the existing panel and upstream protection.
- Tripping characteristic: 7 mm — Record it with the other nameplate data when sourcing a replacement.
- Humidity: 5 % ... 95 % (non-condensing) — Confirm the revision of the installed unit before a like-for-like replacement.
