Table of Environmental Correction Factors

(Derating Factor)
(3A-4A)×1.2, (5A-30A)×1.12

The time current characteristic curve depends on the ambient temperature prevailing. In order to eliminate nuisance tripping. Please multiply the current brea ker current ratings by the derating factor shown below
Normal Continuous Current= 10A
Ambient Temperature = 45 °C
Multiplication Factor = 0.85
Recommended Rating=10A/0.85=11.8A
Select the Nea rest Rating = 12A
