Aerospace series. Circuit breakers. Test methods - Insulation resistanceWhat is BS EN 3841 302 Circuit breakers insulation resistance test about? Aerospace components need to meet the highest quality standards due to the extreme conditions that they are exposed to. The BS EN 3841 series discusses circuit breakers for aerospace applications. BS EN 3841 302 specifies a method of verifying the insulation resistance of circuit breakers which acts as a preventive measure to ensure defects are spotted during the testing process
