Values follow the SICK Connection system accessory specification for this catalog number; parameters not confirmed for this variant are omitted rather than estimated.
The CS81-P3612 is the device-level element in a SICK circuit breaker installation. It receives the field signals and control supply listed above — <= 440 V AC — and switches or conditions the load within the <= 440 V AC 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.
