Thermal Automotive Circuit Breaker 129-L11-H-KF Typical time/current characteristics at +23 °C/+73.4 °F Trip time in seconds Internal connection diagram The time/current characteristic curve depends on the ambient temperature prevailing. In order to eliminate nuisance tripping, please multiply the circuit breaker current ratings by the derating factor shown below. See also section Technical information. Ambient temp. °F -40 °C -40 2 Derating factor This is a metric design and millimeter dimensions take precedence ( mm ) inch All dimensions without tolerances are for reference only. In the...
