Overview
Isolated reverser kit for the Allis-Chalmers TLH-21 load tap changer — all contacts and hardware of the standard kit plus the reversing switch contact finger support and reversing switch assembly. For LTCs requiring full reverser-side replacement.
Why replace worn LTC contacts
Worn or burned tap-changer contacts raise resistance, run hot, and can lead to tap-changer failure. Precision replacements restore reliable switching and extend the service life of the LTC.
