Application envelope
This XT1C 160 variant can be evaluated for three-pole feeder or equipment protection where its voltage and fault interruption capability match the installation. Protection studies should account for conductor ampacity, motor or transformer inrush, downstream selectivity and the upstream device. A frame-size match alone is not an electrical equivalence check.
- Confirm the process or load duty.
- Match the exact code and interfaces.
- Verify protection, approvals and lifecycle status.
Model family references
The following model references belong to the same identifiable family as XT1C 160 TMD 125-1250 3P F F; they are configuration alternatives, not automatic substitutes. Compare each complete designation and application before selecting.

For the XT1C 160 TMD 125-1250 3P F F record, retain the full type string and do not infer range, rating or compatibility from a shortened family code.
Order-code review
For XT1C 160 TMD 125-1250 3P F F, verify rated operational voltage, Icu/Ics, thermal setting, instantaneous threshold, terminal kit, mounting style and any required auxiliary or trip accessories. Confirm the switchboard's busbar and clearance arrangements. Match the exact suffix and ABB order number rather than selecting from a shortened XT1C label.
Commissioning record
Isolate the switchboard, rack or mount the breaker only as designed, and observe the manufacturer's handling and torque instructions. Check trip-unit settings, terminal connections, interlocks and accessory wiring. Complete the approved injection or functional test and retain the exact breaker configuration and coordination record.
For procurement, quote the complete designation XT1C 160 TMD 125-1250 3P F F and state the required quantity, destination, duty and delivery window.
