Claim:
1. A surge protector having a hot line, a load line, a neutral line, and a ground line, the surge protector comprising: a fuse coupled between the hot line and the load line; a differential mode protection circuit coupled between the load line and the neutral line; a common mode protection circuit coupled to the load line, the neutral line and the ground line, wherein the common mode protection circuit includes a first transient suppressor coupled between the load line and an intermediate point, a second transient suppressor coupled between the neutral line and the intermediate point, and a third transient suppressor coupled between the ground line and the intermediate point; and an indicator circuit, the indicator circuit coupled at least between the hot line and the neutral line and capable of indicating an operational status of the surge protector, the indicator circuit including a delay circuit coupled between the load line and the neutral line capable of delaying an output voltage raise of a full bridge rectifier circuit.
