PLATFORM BRANCHES AND REVIEW POINTS
- 01
VXA / VXB
For AC railway traction applications only.
- 02
Rating-range review
Rated voltage, current and breaking duty must be checked within the same technical branch and never combined across branches.
- 03
Mounting and switchgear interface
Confirm fixed or withdrawable construction, primary interface, phase distance and cradle against the actual switchgear.
- 04
Auxiliary circuits and interlocking
Review auxiliary voltage, coils, charging mechanism, secondary plug and interlocking with the project documentation.
