Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The X20PS9402 is the device-level element in a B&R circuit breaker installation. It receives the field signals and control supply listed above — 24 VDC supply module for bus controller, X2X Link power supply and I/O — 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 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Industrial X20PS9402 — Industrial automation component supplied as a like-for-like replacement, selected by catalog number and published ratings. The figures below are taken from the specification table on this page for catalog number X20PS9402; record the nameplate data of the unit being replaced before selecting an equivalent.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Q.For X20PS9402, what does the specification table state about operating temperature?
The specification table lists operating temperature = -25...+60 °C for Industrial X20PS9402. Check the revision of the installed unit if the catalog number has been superseded.
Q.Which value is published under certifications for catalog number X20PS9402?
For X20PS9402, certifications is given as CE, UL, cULus. Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering X20PS9402, which breaking capacity Icu/Ics entry should be checked?
The breaking capacity Icu/Ics entry quoted above is Short-circuit proof, temporary overload. Confirm this figure against the unit currently in the panel.
Q.How do I confirm compatibility of X20PS9402 before ordering?
