保护应用：

与交流干线（120 to 250VACrms）直接连接的产品常会比直流电流输入产品更易接触严峻的浪涌瞬态环境（如雷电、负荷切换等），遭遇短路和过载情况的可能性也更大。 因此，保护器件的功能需要更为强大。

解决方案说明：

As shown at the left (top), a cartridge or leaded fuse (5x20mm, 2AG, 3AG, TE5/TR5) can be used for short circuit and overload current conditions. For surge protection, an MOV (e.g. C-III, UltraMOV and LA series) with high energy handling capabilities should be used. For products that also require electrical isolation between the hot and neutral lines and chassis (earth) ground, a GDT should be selected (left, bottom). The GDT is used to provide electrical isolation for the safety of the consumer.
