    • Material composition:​ Zinc-plated steel bolts and brackets, stainless trim washers, nylon locking nuts, insulated shoulder washers where required, plated mounting clips
    • Finish:​ Anti-corrosion plated / painted hardware matching GE breaker enclosures
    • Operating environment:​ Switchgear ambient –10 °C to +55 °C, indoor ventilated enclosure
  • Structural Features:
    • Contains breaker-retaining bolts, cell-mounting brackets, handle/door-interlock hardware (variant dependent)
    • Designed to lock breaker frame to vertical bus structure without distorting insulation barriers
    • No live conductors, terminals or electronic parts inside the kit
  • Functional Features:
    • Restores original GE torque-secure mounting interface during breaker replacement
    • Prevents breaker rocking, misalignment with stab/bus connections and door-interlock drift
    • Matches GE original enclosure drill pattern for TKM12/THKM12 cells
  • Application Scenarios:
    • 1200 A GE TKM breaker replacement in motor control centers and feeder cells
    • Switchgear refurbishment where original mounting hardware is corroded or lost
    • Outage scope that requires breaker draw-out, bus inspection and re-seating
  • Installation Requirements:
    • Install with breaker in disconnected/draw-out position and enclosure locked out
    • Use supplied hardware only; do not mix with non-GE longer bolts that can penetrate insulation
    • Torque all mounting bolts to GE TK-breaker manualvalues
    • Verify door/interlock linkage travels freely after kit installation
    • Confirm breaker stabs align with bus before racking in
  • Usage Precautions:
    • This is a mechanical kit, not a current-carrying part; never use as bus splice or ground jumper
    • Keep small hardware in original bag until point of use to avoid FOD (foreign object debris) in switchgear
    • Inspect insulation barriers and breaker frame for damage before reusing kit hardware
    • Dispose of deformed or thread-stripped bolts; do not reuse locking nuts
