Siemens Energy and Automation, Alpharetta, Ga., will become the primary automation and controls vendor for Crum Electric Supply, Casper, Wyo., at that distributor's locations in Rock Springs, Evanston, and Gillette, Wyo., and Rapid City, S.D. Those locations previously carried Rockwell Automation/Allen-Bradley (A-B) automation products.

Siemens will now be the main automation and controls vendor at 10 of Crum Electric Supply's 12 locations. General Electric is the main automation vendor at the distributor's other two branches.

“Siemens has been a strong supporter of Crum Electric Supply. With the addition of these four markets it further strengthens our relationship, supports recent acquisitions and ongoing expansion efforts,” said Crum Electric Supply President Jeff Hockin.

Crum Electric took on the A-B line more than 20 years ago. A 1987 acquisition helped solidify the companies' business relationship, but Hockin said Crum Electric carried Allen-Bradley at at least one location before that. Hockin said he does not know who will have the area of primary responsibility (APR) for Rockwell/Allen-Bradley in the markets where his company switched to Siemens.
