OS125GD02P disconnect selection for local isolation and maintenance
OS125GD02P is an ABB OS-series switch-disconnector designation in the 125 A frame class. The exact pole configuration, utilization category, fuse compatibility and handle arrangement must be verified from the product label and ordering documentation. OS125GD02P is primarily an isolation/switching choice; it should not be assumed to provide overcurrent protection unless the exact fuse-switch configuration includes it.

For the OS125GD02P record, retain the full type string and do not infer range, rating or compatibility from a shortened family code.
Configuration boundary
Check OS125GD02P pole configuration, terminal orientation, operating handle, shaft length, enclosure rating, fuse base (if applicable) and line/load arrangement. Confirm the required isolation standard and short-circuit coordination with the protective device. A familiar OS-series designation does not confirm every accessory or enclosure combination.
Consider OS125GD02P where a visible, lockable or interlocked isolation point is required for a feeder or equipment section. Review normal switching duty, fault withstand, upstream protective device and the maintenance procedure. The isolator must be selected for the circuit's voltage and load category rather than only the nominal frame number.
Safe return to service
Before fitting OS125GD02P, isolate the supply and verify the switching mechanism is in the correct position. Align the handle and shaft, check door interlock operation, verify contact state and tighten conductors to ABB values. Test lockout provision and safe isolation indication before handover.
Keep the verified order information for OS125GD02P with the panel drawing, commissioning record and maintenance history.
