Where it sits in the control system
The KN5102 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 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 KN5102
IFM KN5102 Capacitive Sensor. See the manufacturer product information for this catalog number.
- Dimensions (H x W x D): M30 x 1.5 / L = 100 — Confirm the revision of the installed unit before a like-for-like replacement.
- Certifications: CE, cULus — Use it as the reference when cross-checking a current-production equivalent.
- Operating temperature: -25...+60 °C — Verify it in the project documentation before confirming the order.
- Overload capacity: yes — Check this value against the nameplate of the installed unit before ordering.
Cross-check the ratings above with the installed device before confirming the order.
Common questions about KN5102
Q.Before ordering KN5102, which overload capacity entry should be checked?
The overload capacity entry quoted above is yes. Check the revision of the installed unit if the catalog number has been superseded.
Q.Where can I find the operating temperature data for KN5102?
It is listed in the specification table for IFM KN5102 as -25...+60 °C. Compare it with the nameplate of the installed unit before ordering.
Q.For KN5102, what does the specification table state about dimensions (H x W x D)?
The specification table lists dimensions (H x W x D) = M30 x 1.5 / L = 100 for IFM KN5102. Confirm this figure against the unit currently in the panel.
Q.What should I include in an enquiry for KN5102?
Send the full catalog number KN5102, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for IFM KN5102.
Q.How do I confirm compatibility of KN5102 before ordering?
Match the catalog number KN5102 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
