ABSTRACT:
A circuit protection device includes a case having a transverse top portion provided with a central receiving opening and two locating holes, and two wall portions downward extended from a middle part of the transverse top portion to define a receiving space therebetween for communicating with the receiving opening and locating holes; a cutout unit having two conducting plates connected via a bridge portion, and being inserted in the receiving space with the conducting plates engaged with the locating holes and partially projected from two longitudinal edges of the wall portions; and a bipolar LED mounted in the receiving opening and having a conducting portion in contact with two pins of the cutout unit, and a light source. In an overcurrent state, the bridge portion is burned out, and current flows through the bipolar LED for the same to emit light as a cutout warning signal.
