Home Electrical Engineering Forum General Discussion Lightning & Surge protection Re: Lightning & Surge protection


The information you include about SPD´s iwill mislead the opinion of

because there´re manufacturers that had consider the problem and
include a fuse in front
of each MOV, designed to open the circuit in case of a failure or end of life of the varistor.

but it´s not any fuse, because it goes in the protection module in front of each MOV. On the other hand a limiting fuse for protection will jeopardize the function of the SPD
