Most of the Siemens Allis and Allis Chalmers work we do involves contacts and disconnect finger clusters from air circuit breakers and oil circuit breakers. We also repair and manufacture contacts to tap changers, especially those to the TLH-21 series. To the right are two stationary reversing contacts and a reversing contact assembly from a TLH-21 tap changer.

We also do a lot of repair work on finger clusters like those shown in the photos below. Need finger clusters? We can often supply these at competitive prices. Visit the Warehouse link in the above tool bar for more information on the 1200 AMP and 4000 AMP round finger clusters or use the information at the bottom of this page to call for a quote today!
