Table of Enviromental Correction Factors
Operating Factor

-5°C	(3A-4A) * 1.25, (5A-30A) *1.13
+40°C	(3A-4A) * 0.91, (5A-30A) * 0.93

*Remarks:
(1)The time / current characteristic curve depends on the ambient temperature prevailig.
(2) In order to eleminate nuisance tripping, please multiply the breaker`s current rating by the derating factor show  below:
Example:
Normal Continouse Current = 10A
Ambient Temperature = 40°C
Multiplication Factor = 0.94
Recommended Rating = 10A / 0.94 =10.6A
Select the Nearest Rating = 11A

Time current characteristic curve (+25°C)

100% Rated Current: No tripping within 1 hour;
135% Rated Current: Tripping within 1 hour;
200% Rated Current: Tripping within 40 Seconds.
300% Rated Current: Tripping within 10 Seconds.
