Breaker contact
WebA contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a … WebFor example, a circuit breaker with pole resistance readings of 50, 60, 76 milli-ohms would “fail” the test but a circuit breaker with 130, 180, and 150 milli-ohms resistance would pass. A second evidence is the observable weak correlation between new-circuit breaker pole resistance testing and temperature in service.
