Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 2861852 is the device-level element in a Phoenix Contact circuit breaker installation. It receives the field signals and control supply listed above — 7.5 V DC (via voltage jumper) — 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 / panel support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Phoenix Contact 2861852 — Industrial automation component supplied as a like-for-like replacement, selected by catalog number and published ratings.
