J553_199206 CIRCUIT BREAKERS

This SAE Standard defines the test conditions, procedures, and performance requirements for circuit breakers in ratings up to and including 50 A. The document includes externally or internally mounted automatic reset, modified reset, and manually reset types of circuit breakers for 12 V and 24 V DC operation. Some circuit breakers may have dual voltage ratings (AC and DC), however, this document evaluates DC performance only.
