ABB OT25F3 field acceptance and specification notes
ABB OT25F3 selection begins with the exact device identity and its assigned function. The values in the following table are a starting point for checking the delivered unit, not a substitute for the nameplate.
Technical identification and decision points
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | OT25F3 |
| Product family | OT25F3 |
| Component role | compact three-pole switch-disconnector |
| Type | OT25F3 |
| ABB order code | 1SCA104857R1001 |
| Poles | 3 |
| IEC current class | 25 A |
| UL/CSA current | 30 A listing |
| Mounting | Base or DIN rail; handle and shaft separate |
| Final configuration | Confirm exact nameplate, hardware revision and order options before purchase |
Confirm ABB OT25F3 against the current ABB documentation and the actual plant duty. A range or capability from another variant must not be assumed for this exact build.
Interface evidence
Before ABB OT25F3 is ordered, compare current, IEC/UL duty, DIN-rail fit, terminals and handle. Capture the installed nameplate, a clear terminal photograph and the cabinet drawing revision.
A visual resemblance to ABB OT25F3 is not proof of equivalent contacts, voltage, communication, release, connector orientation or certification.
Failure and mismatch review
If ABB OT25F3 was requested after a fault, document the symptom and tests that separated component failure from wiring, supply, configuration or upstream protection problems.
If the delivered ABB OT25F3 differs from the ordered complete designation, hold it for engineering comparison. Do not treat a family name as an interchangeability approval.
Equipment duty and scope
ABB OT25F3 is considered where the site needs to provide local manual disconnection for a small feeder. Record the asset tag, circuit or loop boundary, and reason for the change before specifying a replacement.
The ABB OT25F3 procurement request should distinguish the physical device from any separate accessories, configuration files, protection devices and installation materials.
Commissioning evidence
After fitting ABB OT25F3, check switching position and enclosure access. Use the site's approved safe test procedure and observe all connected interlocks and indications.
Log the ABB OT25F3 serial or revision, test result, date, and witness. Restore normal operating mode only after the relevant process owner accepts the change.
Work package
The ABB OT25F3 work package needs isolation, access, disconnection and restoration steps approved for this plant. Preserve the original wiring marks and any usable settings backup.
During ABB OT25F3 installation, verify adjacent equipment clearance and protective bonding without altering an approved design solely to fit a substitute.
Purchasing handoff
Quote ABB OT25F3 exactly and attach the current ABB reference alongside the equipment label. Ask the supplier to state any order-code, revision or accessory differences.
Keep a traceable ABB OT25F3 comparison with the installed part and require written approval for alternatives that change electrical or control behavior.
Related configurations in this series
These OT25F3 references belong to the same product grouping as ABB OT25F3, but ratings and included parts can differ. Match the entire designation before treating one as a replacement.
No other unassigned OT25F3 reference is grouped with ABB OT25F3 in this release.
Acceptance record
For ABB OT25F3, retain the final order code, supplied revision, installation findings and functional test evidence.
If ABB OT25F3 is rejected or substituted, keep the reason and the approved disposition with the asset record.
