ZJ Auto-Reset AR Auto-Reset 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 = 10A
Ambient Temperature = 45°C
Multiplication Factor = 0.85
Recommended Rating= 10A/0.85=11.8A
Select the Nearest Rating = 12A
