Where it sits in the control system
The 2864684 is the device-level element in a Phoenix Contact circuit breaker installation. It receives the field signals and control supply listed above — 11...30 V DC (loop powered) — 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 DIN rail mounting support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
