Verify model-specific dimensions, terminals and installation requirements in the manufacturer documentation before selecting an alternative.
The KB5056 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 standard panel or DIN-rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.

Cross-check the ratings above with the installed device before confirming the order.
Q.Which value is published under rated operational voltage for catalog number KB5056?
For KB5056, rated operational voltage is given as <= 440 V AC. Check the revision of the installed unit if the catalog number has been superseded.
Q.Before ordering KB5056, which breaking capacity Icu/Ics entry should be checked?
The breaking capacity Icu/Ics entry quoted above is yes. Compare it with the nameplate of the installed unit before ordering.
Q.Where can I find the degree of protection data for KB5056?
It is listed in the specification table for IFM KB5056 as II. Confirm this figure against the unit currently in the panel.
