Heavy-Duty Circuit Breakers(Cancelled May 2013)
J1625_201305
This SAE Recommended Practice defines the test conditions, procedures, and performance requirements for circuit breakers in ratings from 50 to 200 A. The document covers externally mounted automatic reset and manually reset types of circuit breakers for low voltage DC operation (typically 50 V or less).
Rationale:The test specification for SAE J553 and SAE J1625 are almost identical with variation only in the test lead sizes and interrupt test currents that change as the value of the circuit breaker amperage increases.
Manufacturers have adopted the SAE J553 spec in their literature in practice.
One standard will fully support all 12V/24V circuit breaker requirements up to 200A. This will simplify the research for the engineer using SAE standards and remove the possibility of one spec not matching the other.
