Don't let this happen to the surge protector in your home or business. The inexpensive surge protectors use MOV's (Metal Oxide Varistors) to shunt the surge to ground. As the MOV's in these units sacrifice themselves to surges they can become overheated and have caused fires. Visit HL Stores for more information on protecting your computers, HDTV's, plasma TV's, home theaters, TiVo's, satellite receivers, network servers, phone and data systems, CCTV, Alarm Systems, appliances, etc.
