Did you work with Westinghouse De-Ion Arc Chute Plates? According to publicly filed asbestos litigation records, it allegedly contained asbestos. Here is what it was, who was exposed, and who is responsible. Westinghouse De-Ion Arc Chute Plates, sold from the 1930s until the 1980s. Allegedly asbestos-containing molded arc-quenching plates and side liners inside Westinghouse De-Ion arc chutes, according to publicly filed asbestos litigation records. Allegedly molded chrysotile-reinforced arc-quenching plates and side liners used inside De-Ion arc chutes on air-magnetic circuit breakers, MCCs, and starters.

Product Description
The Westinghouse De-Ion arc chute was the flagship arc-interrupting assembly used across Westinghouse air-magnetic circuit breakers, magnetic contactors, motor starters, and low-voltage switchgear from the 1930s through the early 1980s. According to publicly filed asbestos litigation records, the stacked “grid” plates and side liners that split and cooled the arc were allegedly molded from chrysotile-reinforced phenolic or refractory composition, chosen for its dielectric strength and ablative resistance to repeated arcing.
Every time a De-Ion breaker interrupted a fault, the arc allegedly eroded the plate faces, releasing asbestos-laden dust into the breaker cubicle.
Workers Exposed
- Industrial electricians (IBEW) who racked, tested, and maintained Westinghouse air-magnetic breakers
- Substation electricians rebuilding De-Ion chutes in-place at utility and industrial switchyards
- Motor control center technicians replacing arc-chute stacks on Westinghouse starters
- Arc-flash repair technicians cleaning cubicles after fault-clearing events, allegedly disturbing eroded asbestos plate residue
