All variants share the same B&R X20 I/O module footprint and terminal layout; the columns above show where they differ. Selecting a different catalog number changes the electrical interface, not the mounting.
The X20BT9300 is the device-level element in a B&R circuit breaker installation. It receives the field signals and control supply listed above — 24 V DC (IEC 61131-2) — and switches or conditions the load within the the rated 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.
Q.What supply does this device require?
It requires 24 V DC (IEC 61131-2). Size the supply source to the same rating shown in the Specifications table.
Q.How is this device mounted?
It mounts by 35 mm DIN rail (IEC 60715). Confirm the cutout or rail before ordering a like-for-like spare.
Q.What is the operating temperature range?
The confirmed operating range is 0...+55 °C (IEC 60068-2-1). Panels running beyond it need derated sizing.
Q.What replaces a unit that is no longer in production?
For a like-for-like spare, record the catalog number and revision from the nameplate; a current-production equivalent is identified by matching function and ratings.
