A protective circuit for thunderbolt abrupt waves includes an excessive current protector and an abrupt absorber. The excessive current protector is a single or plural strand metal lend, The single strand metal lead possesses a diameter in the range of 0.23 mm-0.35 mm, and the plural stand metal lead has a cross-sectional area in the range of 0.0415 mm<SUP>2</SUP>-0.0962 mm<SUP>2</SUP>. So on one hand, the abrupt wave absorbers can surely serve its duty, and the other hand, the metal lead can be molten in case of abnormal current so as to protect the abrupt wave absorbers from burning up or exploding.
