Abstract
An arc motivating assembly positioned on both sides of a pair of circuit breaker contacts is coated with electrical insulating material arranged in alternate layers of two different compositions. The first is selected to have good electrical insulation and high arc resistance, and the second is selected for vaporizing and generating gases to assist in arc blow out and extinction.
