Fusing characteristics

 
Shall comply with the following provisions under the condition of overload fuse time at rated current rate specified (0.25W R<1 rated current ratio for 30 times. The R more than 1 ohm rated current ratio for 36 times. The fuse time less than 60 seconds. 0.5-3W R<1 rated current ratio for 30 times. The R more than 1 ohm rated current ratio for 36 times. The fuse time less than 60 seconds. 1WS-3WS R<1 rated current ratio for 30 times. The R more than 1 ohm rated current ratio for 36 times. The fuse time less than 60 seconds. Note: the fusing characteristics can be made according to the requirements of the customer and the product which is required to be struck by lightning does not examine the time of fusing or according to the requirements of the customer.
