Fusing Current
(A)
Ambient Temperature
(°C)
Stationary Current: Regard the peak of stationary current waveform as
stationary current value when the stationary current is repeated pulse.
Normal derating of this product should be 0.7max. as standards.
Deratings by ambient temperatures.
When using the products at the temperatures other than normal
temperature (25°C ± 5°), temperature adjustment will be required.
Please refer the derating coefficient as shown in the figure.
