SAE J 1625:2013 PDF Download

The SAE J 1625:2013 standard provides guidelines for circuit breakers with ratings ranging from 50 to 200 A. The standard outlines the test conditions, procedures, and performance requirements for these circuit breakers. It specifically focuses on both externally mounted automatic reset and manually reset types of circuit breakers designed for low voltage DC operation, typically 50 V or less.

The standard aims to ensure that heavy-duty circuit breakers meet specific criteria to ensure their safe and reliable operation. By specifying the test conditions and procedures, the standard provides a consistent and standardized approach to testing these circuit breakers. It also sets performance requirements that circuit breakers must meet to ensure they are capable of effectively interrupting a current flow in a low voltage DC system.
