Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.

Where it sits in the control system

The X20DO4331 is the device-level element in a B&R circuit breaker installation. It receives the field signals and control supply listed above — <= 440 V AC — 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.

Selection notes for Industrial X20DO4331

Industrial X20DO4331 — 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 X20DO4331; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.

• Operating temperature: -25...+60 °C — Record it with the other nameplate data when sourcing a replacement.
• Breaking capacity Icu/Ics: &lt;24 A — Confirm the revision of the installed unit before a like-for-like replacement.
• Certifications: CE, UL, cULus — Use it as the reference when cross-checking a current-production equivalent.
• Output current: 2 A — Verify it in the project documentation before confirming the order.

For a discontinued unit, match function and electrical ratings rather than the label alone.
