Scope:

This SAE Standard defines the test conditions, procedures, and performance requirements for circuit breakers in ratings up to and including 200 A. The document includes automatic reset, modified reset, and manually reset types of circuit breakers for 12 V and 24 V DC electrical systems. Some circuit breakers may have dual voltage ratings (AC and DC), however, this document evaluates DC performance only.

Rationale:

Incorporated requirements of SAE J1625 (Heavy-Duty Circuit Breakers). Changed references that have become obsolete. Clarified use of power supplies vs. batteries, and test condition details. Added monitoring of current during failure (interrupt test) to better capture actual failure mode.
