factor
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.
Example : Normal Continuous Current = 50A
Ambient Temperature = 45°C
1 2 Multiplication Factor = 0.85
Recommended Rating= 50A*0.85=58.8A
