Where it sits in the control system
The KI0041 is the device-level element in an IFM circuit breaker installation. It receives the field signals and control supply listed above — 10...30 V DC (IEC 60947-5-2) — 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 non-flush mountable support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for IFM KI0041
IFM KI0041 Capacitive Sensor. See the manufacturer product information for this catalog number.
- Certifications: CE, cULus — Match it to the existing panel and upstream protection.
- Frequency: 25 — Record it with the other nameplate data when sourcing a replacement.
- Rated operational voltage: <= 440 V AC — Confirm the revision of the installed unit before a like-for-like replacement.
- Operating temperature: -25...+60 °C — Use it as the reference when cross-checking a current-production equivalent.
Cross-check the ratings above with the installed device before confirming the order.
Common questions about KI0041
Q.Which value is published under breaking capacity Icu/Ics for catalog number KI0041?
For KI0041, breaking capacity Icu/Ics is given as no. Confirm this figure against the unit currently in the panel.
Q.Before ordering KI0041, which supply voltage entry should be checked?
The supply voltage entry quoted above is 10...30 V DC (IEC 60947-5-2). Use the value as the reference when sourcing a current-production equivalent.
Q.Where can I find the overload capacity data for KI0041?
It is listed in the specification table for IFM KI0041 as no. Check the revision of the installed unit if the catalog number has been superseded.
Q.How do I confirm compatibility of KI0041 before ordering?
Match the catalog number KI0041 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
Q.Can the KI0041 replace the unit currently installed in my panel?
Compare catalog number KI0041 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.
