Where it sits in the control system
The KN5106 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 KN5106
IFM KN5106 Capacitive Sensor. See the manufacturer product information for this catalog number.
- Frequency: 5 — Match it to the existing panel and upstream protection.
- Breaking capacity Icu/Ics: yes — Record it with the other nameplate data when sourcing a replacement.
- Overload capacity: yes — Confirm the revision of the installed unit before a like-for-like replacement.
- Mounting: non-flush mountable — Use it as the reference when cross-checking a current-production equivalent.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Common questions about KN5106
Q.Which value is published under dimensions (H x W x D) for catalog number KN5106?
For KN5106, dimensions (H x W x D) is given as 78 x 36 x 10. Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering KN5106, which frequency entry should be checked?
The frequency entry quoted above is 5. Confirm this figure against the unit currently in the panel.
Q.Where can I find the operating temperature data for KN5106?
It is listed in the specification table for IFM KN5106 as -25...+60 °C. Use the value as the reference when sourcing a current-production equivalent.
Q.How do I confirm compatibility of KN5106 before ordering?
Match the catalog number KN5106 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 KN5106 replace the unit currently installed in my panel?
Compare catalog number KN5106 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.
