One set covers three poles
The documented set contains three movable and six stationary contacts with springs. That is one coordinated three-pole renewal set, not a single contact tip and not one package per pole. Inspect all poles because uneven wear or damage elsewhere can affect the repair scope.
Do not file away the contact surface
ABB instructs replacement when nearly all silver tip material is gone and says not to file or dress the contacts. Surface appearance alone should be judged in the context of remaining material, alignment, pressure, overheating, and the condition of the operating mechanism.
The kit does not include every damaged part
The set is a renewal item for the contact surfaces in the Size 4 starter context. A cracked cover, bent arm, damaged retainer, burnt terminal, weak mechanism, or contaminated magnet structure may require parts beyond this kit. Send wide and close photographs.
