Manufacturer Background

Eaton Corporation, as successor-in-interest to Cutler-Hammer, Inc., is one of the principal U.S. manufacturers of electrical-distribution equipment including transformers, switchgear, motor starters, contactors, and circuit breakers. Cutler-Hammer’s product line is allegedly named throughout publicly filed U.S. asbestos litigation as containing asbestos-bearing components manufactured during the 1950s-1980s asbestos era — including in the Duke v. CBS Corporation et al. case (Cause No. 1822-CC00339, City of St. Louis MO). Per publicly filed allegations, Cutler-Hammer transformers, switchgear, and motor starters manufactured during the asbestos era allegedly incorporated asbestos-bearing phenolic spacers, Bakelite-type laminate, asbestos transformer paper, asbestos cloth, asbestos gaskets, asbestos arc-chute components, and phenolic-asbestos bushings consistent with industry practice during the era.

How Workers Were Exposed

Per publicly filed allegations in U.S. asbestos litigation, workers were allegedly exposed to Eaton Corporation / Cutler-Hammer asbestos-bearing transformer components during:

  • Transformer assembly at Eaton Corporation / Cutler-Hammer plants — handling phenolic spacers, asbestos paper, Bakelite-type laminate, gaskets, and asbestos cloth during new-transformer construction
  • Transformer dismantling and rebuild at service centers — extracting aged asbestos components from field-aged Eaton Corporation / Cutler-Hammer transformers (highest documented exposure category)
  • Coil-winding operations — fitting asbestos transformer paper and phenolic spacers during winding assembly
  • Machining and trimming — drilling, sawing, and finishing operations on cured phenolic and asbestos-bearing laminate
  • Field maintenance and substation service — utility substation electricians, lineworkers, and industrial electricians handling Eaton Corporation / Cutler-Hammer transformers during in-service repair
  • Reconditioning operations — heat-baking, vacuum drying, and oil refilling of disassembled transformer units saturated with asbestos fiber
