Cutler-Hammer Inc. was one of the United States’ largest manufacturers of industrial electrical controls — motor starters, circuit breakers, contactors, and switchgear. The company manufactured these products using asbestos-containing phenolic molding compounds, which provided the electrical insulation, heat resistance, and structural properties required for electrical control equipment.

Cutler-Hammer was acquired by Eaton Corporation in 1978. Eaton carries successor liability for Cutler-Hammer’s asbestos-era operations.

Asbestos use period

Cutler-Hammer used phenolic molding compounds containing asbestos from the 1930s through the mid-1970s, when asbestos-free phenolic formulations became commercially available. The company was a high-volume consumer of asbestos-phenolic compounds given the scale of its electrical control manufacturing.

Documented facilities

  • Bowling Green, Kentucky — Electrical equipment manufacturing, specifically named in asbestos litigation records as a site where workers were exposed to asbestos-containing phenolic molding compounds
  • Milwaukee, Wisconsin — Cutler-Hammer’s historic headquarters and major manufacturing center
  • Additional facilities across the United States

Products manufactured with phenolic compounds

  • Industrial motor starters and contactors
  • Circuit breakers and enclosed circuit breakers
  • Pushbutton stations and operator controls
  • Panelboards and switchgear
  • Limit switches and safety switches

Worker exposure pathways

Workers at Cutler-Hammer facilities were exposed to asbestos from phenolic molding compound during:

  • Compound handling — receiving, storing, and loading granular phenolic compound into press equipment
  • Compression molding — operating presses that cured the compound under heat and pressure, releasing fine dust when molds were opened
  • Trimming and deflashing — removing mold flash from finished parts with hand tools, generating abrasive asbestos-laden dust
  • Machining — drilling, tapping, and routing cured phenolic parts to produce finished electrical components

The Bowling Green, KY facility is documented in publicly filed asbestos litigation as a site producing occupational mesothelioma cases among workers who handled phenolic compound.

Successor liability

Eaton Corporation acquired Cutler-Hammer in 1978 and is the active defendant for Cutler-Hammer asbestos claims.

If you worked at Cutler-Hammer or Eaton

Workers in molding, trimming, or machining operations at any Cutler-Hammer facility during the asbestos era may have been exposed to asbestos from phenolic compound.
