ABB 2CDH700901R0001 technical selection record
ABB 2CDH700901R0001 is the representative reference for the S750DR-AUX series. Its decision starts with the intended duty: provide breaker state feedback. The technical values below identify this representative, not every series variant.
Technical reference for the representative
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | 2CDH700901R0001 |
| Product family | S750DR-AUX |
| Component role | auxiliary contact for S750DR |
| Exact ABB order reference | 2CDH700901R0001 |
| ABB product series | S750DR-AUX |
| ABB type | S750DR-AUX |
| Contacts | Two changeover contacts |
| Final configuration | Confirm exact nameplate, hardware revision and order options before purchase |
Use the delivered ABB 2CDH700901R0001 marking and current manufacturer documentation to confirm all limits and options before engineering approval.
Decision 2 — compare electrical and mechanical interfaces
Before specifying ABB 2CDH700901R0001, verify S750DR compatibility and signaling wiring. Compare drawings and the real installation, including terminals, clearances, mounting and the relevant supply.
The ABB S750DR-AUX family contains order references with possible differences. For ABB 2CDH700901R0001, a matching series name is insufficient without a full rating and connection check.
Decision 1 — identify the actual function
For ABB 2CDH700901R0001, document the existing device's job, connected circuit and expected behavior. The auxiliary contact for S750DR description helps browsing, but does not prove interchangeability.
Check whether ABB 2CDH700901R0001 is a direct maintenance replacement or part of a revised design. Treat any changed function as an engineering decision.
Decision 4 — receive and inspect
When ABB 2CDH700901R0001 arrives, compare the nameplate and order code with the purchase record. Check housing, connectors and supplied accessories for damage or omissions.
Place ABB 2CDH700901R0001 on hold if the delivered marking differs from the accepted specification. Resolve the difference before installation.
Decision 3 — document procurement boundaries
Quote ABB 2CDH700901R0001 with its complete designation and the approved series, function and application. Ask suppliers to identify every proposed change to current rating, options, firmware or accessories.
Keep ABB 2CDH700901R0001 separate from apparently similar products in another ABB series. Cross-series pairing requires explicit manufacturer compatibility evidence.
Decision 6 — plan a future replacement
A later replacement of ABB 2CDH700901R0001 must be checked again for series, interfaces, ratings and approvals. The related references below are useful for enquiry, not automatic substitutes.
If ABB 2CDH700901R0001 is unavailable, request a written comparison and repeat acceptance testing for any proposed alternate code.
Decision 5 — commission and retain evidence
Install ABB 2CDH700901R0001 only under the approved isolation and commissioning procedure, then operate breaker and verify each contact transition. Record observed results against the design intent.
Store the ABB 2CDH700901R0001 test record with the asset tag, drawing revision and order history so a later technician can verify the exact configuration.
Release criterion
Approve ABB 2CDH700901R0001 after the identity, duty, interface and site test all agree with the approved specification.
Keep ABB 2CDH700901R0001 and its exact order reference on the final equipment record; series grouping is for navigation and selection review.
